New Study reveals CV lies are Rife among Brits
A whopping 38 percent of job seekers admit to’improving’ their own CVs.
So what should you have never been a voluntary aid employee; went the world or worked with underprivileged kids? It transpires that embellishing experience with CV lies comes easily to many.
But who are these liars?
The greater earning bracket admits to being economic with the truth due to the competition they face from the career market.
1 in 3 Brits have lied on their CVs at least once and 1 in 4 do it regularly. Men come out in addition to 42 percent confessing to telling enormous black lies. Whereas 66 percent of girls have never been untruthful, citing fear of being found out. More than 50% of men who confessed to lying do not feel guilty about it.
City employers beware! 44 percent of those who have told porkies live at London and 44 percent, at the Yorkshire and Humber region.
The Scots are bastions of truth with 74 percent of these having never had their pants on fire, being entirely honest on their CVs.
Conversely 33 percentage of earners are more likely to have long noses acquired through lying about their actions outside of work. This group believes that work experience and qualifications are not sufficient to be chosen for a position.
If nothing else, this study confirms that recruiters should never rely solely upon a piece of paper, which could easily be half fiction.
The consequence of CV is located
Employment application fraud is enormous in the united kingdom. This could possibly be a result of the competitive job market, since there are frequently over 200 candidates for any position. However, lying in your CV is a criminal offence (Fraud Act 2006) with a maximum duration in prison of 10 years if you’re caught.
Employers are also becoming savvier, especially in jobs where safety is important, when individuals are working with kids or in the care of their elderly. Candidates could be asked to take a lie detector test, even when other tests are carried out.
The moral of the sorry state of events, called a”sea of lies” by one of the creators of Job Today, is don’t lie on your CV!
Case Study: False Allegations on Social Media
If a person makes false allegations on social websites, the information can spread very quickly not only just to your friends and family potentially causing a lot of upset. There have even been cases of people taking their own lives when false accusations have surfaced. The worse thing is they are so hard to disprove, well that was until the Polygraph came along. At Lie Detectors UK we love a ‘false allegation’ case, we love to be able to help our clients to set the record straight.
Our client first became conscious of a fictitious allegation when her brother drew her attention to a photograph over a weekend. The photo had the look of a display printing. In the best was our client and in the base was a message saying that she rescued animals to market them to puppy fight organisers.
Since our customer has been a veterinary surgeon, functioning in a high profile clinic, she had been horrified. As opposed to wait for her coworkers and also the senior partner to find out, she immediately tell them about it on the following Monday.
The senior partner was worried about the effect this could have on the tradition. He absolutely believed that this is an untrue allegation. But he believed the best approach to counter possible backlash was to our client to have a lie detector test. It was not only our client’s reputation that may be tarnished but also the the practice.
We obtained details from our customer and discovered that the picture was shared on several social media platforms, the majority of which she didn’t utilize or have accounts . The motivation might have been any number of things. Maybe a pet owner hadn’t been happy with treatment at the practice, or maybe somebody was envious of her achievement. Equally it might have been somebody who has nothing better to do than Photoshop a haphazard image to cause difficulty.
We assured out client that we could help and administered the lie detector test in the day in the clinic, when it was closed. She passed the test with flying colours. Our examiner ascertained that she had never sold puppies to anybody, she didn’t understand any dog struggle organisers and had no link with dog fighting at all.
Our examiner subsequently prepared a report for her so that she can prove her innocence. This report is now available from the veterinary clinic for anybody who cares to visit it.
Social networking could have a place in our society but a lie is now able to travel around the world in minutes. If something is posted/published online it is extremely difficult to get rid of it. A classic example was Lord McAlpine’s name was falsely linked to child abuse on Twitter. His attorneys found around 10,000 tweets and retweets which were sparked by a BBC Newsnight report in which the allegation began. Heads rolled over this using all the BBC Director General, George Entwistle, losing his position and thousands and thousands of pounds being paid in damages. Twitter accounts which had tweeted the lie and people who’d retweeted it were advised to delete them pay a small contribution to charity or be prosecuted for libel.

Covid 19 Update
We have taken the decision to restrict Lie Detector Tests to our head office in Maidstone where we can run a test in a well ventilated room to mitigate any risk. The examiner will be wearing a face mask to protect himself and clients, we will not be running any tests for people with symptoms and we may ask to take your temperature and we will ask you to either wash your hands or use alcohol gel provided. This is purely a measure to restrict exposure and to protect everyone including the NHS who are doing such a great job. Stay safe.
It was interesting to see in the news this week that Charles Honts a professor of psychology at Boise State University who is also on the EyeDetects advisory board looked at recent results and stated he finds the EyeDetect system interesting but on the other hand he doesn’t use it and until its database is expanded and other people have replicated it he would be reluctant to use it in the field. There have been some unsuccessful trials for US Police Forces and limited research which could be why the technology has never gained any popularity in the UK. The UK Government rejected EyeDetect over the Polygraph in recent trials.
Polygraph machines sense changes in respiration, blood flow and skin conductance (a moisture buildup under skin). Thus, a polygraph measures physiological changes when under the stress of questioning. That questioning is intended to determine whether a person is lying or being truthful. EyeDetect measures changes in pupil size and eye movements that reflect the changes in their brain activity while a person reads and responds to a questionnaire. For the polygraph, the primary testing premise is that a deceptive person will show stronger emotional reactions to questions about topics for which they are deceptive. For EyeDetect, the primary testing premise is that a deceptive person will show an increase in cognitive load when questioned about topics for which they are deceptive. Polygraph has the research to prove its accurate when used for single issue testing, we see EyeDetect working as a screening tool. EyeDetect can be used to replace in some circumstances and/or can complement the polygraph. Studies show that the polygraph can be very accurate for event-specific questioning.
Lie Detectors UK continue to keep up to date on within the deception industry to ensure they use the latest and most accurate equipment available today.
Lie Detectors UK offers a range of accurate polygraph test services to help people separate truth from lies in both personal and professional matters.
Laura and Tony got in touch with the company in 2019 because they wanted to move forward as a couple but couldn’t get past accusations of infidelity.
Tony had been cheated on by his two prior partners, and he constantly worried that Laura would cheat on him as well — even though she claimed to be faithful to him throughout their three-year relationship.
The couple requested a Proof of Innocence test for Laura, who wanted to prove her trustworthiness to her partner. The examiner’s questions focused on her sexual activity in the last three years, and the test measured her physiological changes when responding. She was understandably nervous, but that didn’t impact the results: Laura passed with flying colors.
Lie Detectors UK offered Tony proof that Laura had not cheated on him, and that helped the couple work through their issues and address Tony’s trust issues in a non-threatening way.
“The results enabled them to move on in a better relationship,” said Jason Hubble, the Chief Polygraph Examiner and Founder of Lie Detectors UK.
Jason has years of experience administering polygraph tests and examining the results. He’s a member of the British and American Polygraph Association and the Secretary of the UK Polygraph Association. He was the first polygraph examiner to advertise fixed prices, he has delivered polygraph tests on behalf of law enforcement agencies, law firms, employers, and families.
In 2013, Jason founded Lie Detectors UK to make polygraph tests more widely available to the public so everyday people could benefit from the insights they can provide.
About 70% of Cases Involve Accusations of Infidelity
Healthy relationships are built on trust, but sometimes trust isn’t easily given. Some couples have to earn or rebuild trust with one another. Sometimes an individual reaches a breaking point and can’t even trust the word of a significant other. That’s where a lie detector test can come in handy.
Lie Detectors UK can offer a solid foundation to discover who’s trustworthy and who’s not. Its highly attuned polygraph can bring certainty to a lot of murky cases and sensitive subject matters, and it only takes a couple hours to get that clarity.
The test is comprised of three stages — the Pre-Test interview, the Data Collection, and the Post-Test interview. A well-qualified professional walks customers through each stage and helps them understand the results. Lie Detectors UK only runs Single Issue tests because that achieves the maximum accuracy of 92-94%.
A relationship counsellor and polygraph examiner named Norma Phoenix is on the team to provide guidance on personal issues between couples. She is particularly adept at handling cases of infidelity.
Jason estimated that about 70% of customers choose to take the polygraph test to settle questions of infidelity. Many couples see it as a way to verify or discredit claims and put an end to fruitless argument — one way or the other.
Lie Detectors UK won the award for The Best Polygraph Testing Company in 2019, and all its examiners have graduated from training programs accredited by the American Polygraph Association. While the company is based in London, team members conduct polygraph tests throughout Europe and around the world, and they offer professional lie detection services for both personal and business requirements.
“Whilst polygraph has its critics, we continue to see governments increasing its use as it really does work as an effective interrogation tool,” Jason told us. “Nothing else can offer this type of verified accuracy — provided the test is run by a certified examiner.”
Providing Clarity to Couples Grappling With Uncertainty
Lie Detectors UK appeals to couples who have serious disputes and accusations to settle. Infidelity is one of the most common reasons couples seek the polygraph test, and many couples positively review the company and say they got the answers they needed. While the test can’t provide accurate information about someone’s emotions or intentions, it can offer clarity about their actions and whether they’re lying about something they did.
Steve and Sharon had been married for 30 years, and their affection was waning when Sharon noticed Steve starting to care more about his appearance. He exercised more and ate healthier than ever before, and he even bought new underwear, all of which struck her as strange and suspicious.
Sharon couldn’t shake the feeling that Steve was having an affair. When she confronted him about it, he agreed to take a polygraph test to prove his faithfulness.
Lie Detectors UK ran a Proof of Innocence Polygraph Test on Steve. During the Pre-Test Interview, Steve acknowledged that he had changed his lifestyle and understood how that may cause alarm, but he just wanted to take better care of himself. He went on to pass pass the test and prove that he had not had any affairs within the past five years.
Sometimes Lie Detectors UK reaffirms a relationship, as with Steve and Sharon, and other times it identifies deception and misconduct.
Jean suspected her boyfriend Michael was having an affair because she spotted a text message with a kissy face in his inbox, and she didn’t recognize the name or number. Michael was combative and evasive about his relationship with the mystery woman, so Jean decided she needed him to take a polygraph test to suss out what was going on.
Michael failed the polygraph test, and the examiners found strong evidence that he was trying to cheat the test. During the Post-Test Interview, Michael became angry and offered no explanations about his behaviour or apparent lies.
The next day, Jean got in touch with Jason to let him know how everything had unfolded after the couple had left Lie Detectors UK.
Jean said she gave Michael an ultimatum: tell her the truth, or she would sever contact with him for good. He admitted to seeing 13 women on the side. Finally, Jean believed him.
“That man has serious issues,” Jean concluded. “Thanks for saving me from a miserable life.”
Lie Detectors UK Puts Relationships to the Test
Lie Detectors UK strives to answer that age-old question: Can I trust you? The company can help couples, employers, families, and friends discover the truth and get to the root of their most pressing problems and emotional concerns. Some people use the test to restore faith in their relationships, and others use it to prompt admissions of guilt, and both experiences can inform and enlighten the participants involved.
Whether it’s dealing with infidelity, theft, or some other misdeed, the lie detector test has a way of bringing truth to the forefront and creating an open dialogue between key players.
“Very impressed with the service from start to finish,” said the Maxen family in a five-star review. “[Lie Detectors UK] was extremely professional, many thanks! We were expecting an awkward time, but left pleasantly surprised.”
The Confusion between Opinions and Lies
We’ve been looking at comments on news articles and sociable media nowadays. There seems to be much confusion between opinion and lies.
An opinion Isn’t a lie
There are two chief ways that people formulate opinions. Some will read an article or listen to the news and decide whether they think it or not. This really isn’t the ideal method to make an opinion unless you’ve got specific knowledge of the topic. But when something doesn’t make sense it always isn’t sensible! So an opinion may be formed depending on the absence of logic.
The better method is to do a little bit of research and set the details of an issue. When you have the details you are able to think about these, add your own ideas and post your opinion.
Some may elaborate on the reason why they disagree with you and try to change your opinion. Others might suggest you are lying because they can not know how you may potentially have reached your conclusion, given the facts.
A very simple example to demonstrate that the difference between opinions and lies comes from a BBC broadcast from years ago.
Were individuals lying when they said spaghetti grew on trees?
On 1 April 1957 BBC Panorama broadcast a’documentary’ about a Korean family that were seen to be harvesting a’spaghetti tree’. It was possibly among the greatest hoaxes in the history of April Fool’s Day pranks. https://en.wikipedia.org/wiki/Spaghetti-tree_hoax
Very little was known about spaghetti in the UK at the time and it certainly was not readily available as it is now. Canned spaghetti was the closest anyone got to eat a pasta dish in these days.
Following the broadcast, countless audiences known as the BBC. Some asked whether it had been authentic and many sought additional information as to how they might develop a spaghetti tree of their own.
But, it had been the nation media broadcaster and several individuals genuinely believed the content of this documentary. The concept of an organisation like the BBC lying would not have been countenanced.
When talk about growing the trees started between acquaintances and friends, some did not think it was possible but others mentioned the BBC documentary. Those who believed it was possible were stating an opinion based on the’fact’ the BBC said it had been. In this instance the first way of forming an impression comes into play. Some people did not believe it was plausible so therefore did not think it. They were right. But people who did think it weren’t telling lies when they said you could grow the trees. It was their opinion based on which they were told and seen.
Think carefully about opinions and lies
Calling someone a liar on social networking or an article comments session is never going to achieve a good outcome. You might consider something to be a lie but it’s not necessarily clear why someone else doesn’t. You will know it is a lie therefore the best strategy is to determine why you think the article is wrong backed up by credible evidence.
We are living in a world where there’s an overload of information. Almost all we read and listen to has to be researched to confirm its veracity. Short of small red lights flashing each time a lie seems having half of the world take lie detector tests, our quest for the truth is never easy. As humans we do not all think in the same way, even if we’re presented with the same evidence. There’ll always be opinions and lies but our capacity to determine the difference makes for great discussion.Read More
Deception is Part of Human Nature and Animal Behaviour
It can be surprising to many but deception has been a human trait since life began. There is nothing novel about it, and nothing too suggest that it has diminished or increased as time passes. Deceit exists everywhere as a part of human nature and creature behaviour.
One of the main reasons for deception is the fact that it will help all living things to survive. Even a chameleon will change colour to avoid a predator. It is used on the internet to receive a date and it’s practised in business to baffle competitors.
Biologically it can be found across the spectrum of reptiles, birds, fish, mammals, insects and many plants. Invertebrates and bacteria display it too. So we might be forgiven for concluding that where there’s life, there is deceit.
People are the masters of deceit and practice it more often than all other species combined. Our deception is more elegant and we have significantly more reasons to utilise it. Maybe this is because our brains are comparatively bigger and more developed than most species. However, whilst white lies could possibly be acceptable in our society as well as expected or demanded on event, there are situations when lying is individually destructive.
When deception is detrimental, polygraph machines are invaluable in exposing it.
Primitive Procedures of establishing deception
Lie detection technologies is relatively new and certainly more civilised, compared to the historic quest for the truth.
Dry mouth test
By way of instance, the Chinese (around 1000 BC) used a readily available commodity to determine if someone was lying or not. The alleged liar would be required to spend a little time with a mouthful of dry rice and spit it out. If the rice was not moist and stayed dry, it had been considered evidence of deceit and remorse. The physiological basis of this assertion was that anxiety and stress dries the mouth area. Of course there might be a number of explanations for why a defendant may be scared or fearful but irrespective of this, if you failed the dry mouth test, you’d be executed.
Oversaw the pulse
A couple of hundred years later around 300 to 250 BC a Greek doctor (Erasistratus) quantified the pulse in an attempt to discover deceit. In 1921 the identical method would eventually become a part of polygraph exams and is still employed today.
Other uncivilised techniques, contained trials by ordeal. These were especially common in Europe and were occasionally referred to as”Judgements of God”. Defendants were put specific barbaric tasks to show their innocence. Frequently they entailed fire or water. These trials were based on the premise that God would not allow an innocent man to endure. In areas of Eastern Europe, throughout the 11th century, even some suspect had to plunge a hand into boiling water and leave it underwater for a predetermined period of time. In the event the hand surfaced unblemished (that’s impossible) that it’proved’ the accused was naive.
Another impossible evaluation involved cold water. The accused could be placed in a sack that would then be tied with a rope. The sack was submerged in cold water however in case the suspect emerged alive, they’d be judged . It was deemed, that water which is used in baptising, wouldn’t accept the person and therefore they were lying.
You will find various ways the cold water test evolved over years. It was often used on girls suspected of being witches. Who can forget the ducking stools?
From the late 1500s courts in the Netherlands commissioned a college to study the boiling water method and its effectiveness in discovering deception. Logic prevailed and it was decided the test did not prove whether a suspect was lying or not. On the other hand, the cold water system continued to be utilised through the 1700s until it had been abolished.
Walking over hot coals or carrying hot irons for an extended time period were two approaches used to define innocence. If no flaws were evident after the ordeal, they healed quickly, there was no guilt. You may imagine how often that happened!
Luckily, as civilisation progressed and science evolved, people started to appreciate that tests based on divine intervention were unreliable. We have state of the art polygraph machines to determine deception with fully competent and large trained examiners who can achieve accuracy levels of over 90%.

Northumberland Police get a result using the Lie Detector
Congratulations to Northumberland Police Polygraph Examiners, with over 400 sex offenders put back behind bars through the Polygraph program this is another victory.
A pervert who admitted he had raped a child when he was given a lie detector test while under investigation for unrelated sex offences has been jailed for almost a decade.
The 46-year-old, who had 16 illegal images of children on his phone, was asked by the police during the arrest and investigation process if he would participate in a polygraph test.
Newcastle Crown Court heard Nicholson agreed and confessed during the lie detector questioning that he had attacked a girl in his past, while he was living in a bedsit in Sunderland, and told Northumberland Police detectives who she was.
The court heard the victim, who is now an adult, was interviewed by detectives and found the courage to share sickening details of her shocking ordeal.
Nicholson, now of Gatacre Street, Blyth, Northumberland, admitted rape and six offences of indecent assault.
Judge Stephen Earl praised the victim’s courage in providing details of her ordeal when she was approached by the police and jailed Nicholson for nine years and four months with a two-year extended licence period.
The judge said: “It was the police who approached her initially because of the fact he had undertaken a polygraph test in relation to the 2018 offending, unrelated to her.
“A number of people do not do so ever, many people do not do so for a good many years.”
Judge Earl applauded the “inner strength” of the victim in speaking out.
Nicholson must now sign the sex offenders register and abide by the terms of a sexual harm prevention order for life.
The victim said in her impact statement she has managed to make a “healthy life” for herself and is proud of all she has achieved, despite her traumatic past.
She said: “I haven’t let this man’s abuse destroy my life entirely. He stole my childhood but he has not stolen my adulthood.”
Liam O’Brien, defending, said Nicholson had an unhappy childhood and was bullied and had difficulties.
“There appears to be genuine expressions of remorse.
“This came to light because, as part of the police proceedings that followed from him being apprehended for the previous offences, he was asked if he would participate in a polygraph test.
“There was no power of the police to oblige him to do that, they couldn’t force him to do it but he agreed to do it and when it was put to him the polygraph indicated there was perhaps something he would share with the police he told them who they needed to speak to.”
“The victim’s bravery has helped ensure that Nicholson faced justice for his appalling crimes, and we hope she is now receiving any support she needs.
“We would encourage anyone who has experienced sexual abuse to speak out in the knowledge they will be listened to.”
Children can contact Childline 24/7 on 0800 1111. Adults who wish to report abuse or concerns for a child’s welfare can contact the NSPCC Helpline on 0808 8005000.
Why UK Private Detectives use Accredited Lie Detector Test Providers
Lie Detectors UK do quite a few tests every month for Private Detectives that we work closely with, we can help in focusing the enquiry and effectively saving a client money in an investigation.
Private investigators in the United Kingdom provide a variety of solutions to their customers most of that they carry themselves out. But if polygraph services are required professional private detectives employ accredited APA / UKPA lie detector test providers unless they use a qualified examiner in-house who will also be qualified to APA standards.
The most effective private investigation companies employ ex forces personnel and frequently utilize polygraph providers in their pre-employment screening procedure. This ensures that their employees ares of the maximum integrity and quality.
Accredited lie detector test suppliers safeguard your reputation

A standard test will last around as 2 hours. The examiner can go to the client’s home, or should they prefer to one of our offices.
Lie detector test outcomes are not usually admissible in courts unless the judge decides to allow them as part of additional supportive evidence. On the other hand, the results are able to save detectives squandering time when results show that somebody is lying in a case they’ve been requested to work on. The analogy that the customer is always right isn’t necessarily accurate in personal investigation work. If a client is lying from the start, the detective might opt not to take the case.
After each evaluation a complete report is created for the agency. Only the investigator will have sight of their results unless we’re instructed otherwise.
Broadly private investigators mostly work from the following three areas where evaluations can be used to ascertain the honesty of both witnesses or customers:
If a spouse in a marriage or relationship will not have a lie detector test, detectives know that additional, deeper analysis is necessary to prove infidelity or bigamy. However, arrangement to have a test could easily wrap the case up.
Theft in the workplace
Frequently when an employer can not ascertain who is stealing from the, private investigators are hired as’employees’. The detective will work in the company until they establish the identity of a prospective thief. At this stage the alleged perpetrator could be asked to take a test.

Terrorists to take lie detector tests
Is this about time given the sex offender polygraph testing has been so successful in the UK. Lie Detectors UK fully support this move.
Terrorists could be made to take a lie detector test to prove they have reformed and are not planning to carry out another attack.
Plans to introduce “polygraph testing” were announced by the Government as part of a wave of measures being described as a “major overhaul” in the way terrorists are punished and monitored, including tougher sentences to see them locked up for longer.
It is understood there are hopes terrorists who are going to be out on licence could be made to take the test in a similar way to which sex offenders are sometimes questioned to check their behavior.
More details of The Counter Terrorism (Sentencing and Release) Bill have been released after plans for change were put in place in the wake of the latest London Bridge attack and later announced during the Queen’s Speech.
It is less than two months since convicted terrorist Usman Khan embarked on a killing spree armed with two knives and wearing a fake suicide vest after attending a prisoner rehabilitation programme near London Bridge.
– Force dangerous terrorists who receive extended determinate sentences to serve the whole time behind bars.
– Ensure those convicted of serious offences such as preparing acts of terrorism or directing a terrorist organisation would have to spend a minimum of 14 years in jail.
– Scrap early release from jail for those classed as dangerous and handed extended determinate sentences – in which criminals have to spend longer on licence after prison.
– Double the number of counter terrorism probation officers.
– Make more places available in probation hostels so authorities can monitor terrorists in the weeks after they are released from prison.
– Increase counter-terrorism policing funding by £90 million year-on-year for the coming year to £906 million.
– Give an immediate £500,000 cash injection for support for victims of terrorism and a review of services available.
– Provide more specialist psychologists and trained imams who help to assess the risk of radicalised offenders.
– Offer more training for front-line prison and probation staff to identify and challenge extremism behind bars and on licence.
Terrorists deemed not to be a risk would have to serve two-thirds of their sentence before the Parole Board could consider them for release.
Jonathan Hall QC, the independent reviewer of terrorism legislation, will also review the way in which agencies like the police, probation and security services investigate and monitor terrorists – known as Multi Agency Public Protection Arrangements (Mappa).
Home Secretary Priti Patel said: “The senseless terror attack at Fishmongers’ Hall in November confronted us with some hard truths about how we deal with terrorist offenders, which is why we immediately announced a review into sentencing and licence conditions, to do whatever is necessary to stop these sickening attacks from taking place.
“Today we are delivering on those promises.”
Justice Secretary Robert Buckland said: “Terrorists pose a great risk to our society and our way of life, which is why we must bring them to justice and keep the public safe.”
Plans for the Bill were first mooted shortly after the November attack, which claimed the lives of Saskia Jones and Jack Merritt.
At the time Mr Merritt’s father Dave hit out at Boris Johnson, accusing him of seeing an opportunity to score political points during the general election in the aftermath of the tragedy.
Khan, a 28-year-old British national from Staffordshire, had been released from prison on licence in December 2018, halfway through a 16-year prison sentence after he was convicted of terror offences in February 2012.
He was part of an al Qaida-inspired terror group, linked to radical preacher Anjem Choudary, that plotted to bomb the London Stock Exchange and build a terrorist training camp on land in Pakistan-controlled Kashmir owned by his family.
Staffordshire Police is being investigated by the Independent Office for Police Conduct for its role in managing Khan.
In the year to the end of September, there were 44 convictions for terrorism offences, with 17 offenders being sent to jail for between four and 10 years, the Government said.
Five were jailed for 10 years or more and one was handed a life sentence.
Around 245 convicted terrorists were freed from jail between 2012 and 2019.
Shadow home secretary Diane Abbott said the announcement of a security overhaul was “an admission of failure” by the Government.
“Major terrorist outrages have occurred all too frequently, including attacks by perpetrators who were known to the security services,” she said.
Liberal Democrat home affairs spokeswoman Christine Jardine said judges already had the power to lock up terrorists for life while polygraphs were “not accurate or reliable enough” for such critical decisions.
“We will continue to oppose authoritarian laws that do little to make us safer, but a lot to undermine essential British freedoms,” she said.
