MPs are expected to clear the way for the introduction of compulsory lie detector tests to monitor convicted sex offenders across England and Wales from next January.

The national rollout of US-style mandatory polygraph tests for serious sex offenders who have been released into the community after serving their prison sentence follows a successful pilot scheme. The trial was carried out from 2009-11 in two Midlands probation areas and found that offenders taking such tests were twice as likely to tell probation staff they had contacted a victim, entered an exclusion zone or otherwise breached terms of their release licence.

Continuing concerns about the reliability of the tests and misinterpretation of the results mean they still cannot be used in any court in England and Wales.

But it is expected that the compulsory polygraph tests will be used to monitor the behaviour of 750 of the most serious sex offenders, all of whom have been released into the community after serving a sentence of at least 12 months in jail.

The tests involve measuring reactions to specific questions by monitoring heart rate, blood pressure, breathing and levels of perspiration to assess whether the subject is being truthful. The results will be used to determine whether they have breached the terms of their release licence or represent a risk to public safety and should be recalled to prison.

The power to introduce compulsory lie detector tests was put on the statute book six years ago in the Offender Management Act 2007. On Tuesday MPs will debate secondary legislation in the form of a statutory instrument to come into force from 6 January 2014. The House of Lords will be asked to approve it later this month.

The justice minister Jeremy Wright said: "Introducing lie detector tests, alongside the sex offenders register and close monitoring in the community, will give us one of the toughest approaches in the world to managing this group.

"We recently announced the creation of a National Probation Service tasked with protecting the public from the most high-risk offenders. They will be able to call on this technology to help stop sex offenders from reoffending and leaving more innocent victims in their wake."

Hertfordshire police used the tests in a pilot scheme in 2011 to help decide whether to charge suspected sex offenders and gauge the risk they posed to the public. "Low level" sex offenders were involved in the original pilot. At least six revealed more serious offending and were found to pose a more serious risk to children than previously estimated. A further trial was ordered but at the time the Association of Chief Police Officers voiced caution about the adoption of such tests: "Polygraph techniques are complex and are by no means a single solution to solving crimes, potentially offering in certain circumstances an additional tool to structured interrogation," a spokesman said.

Polygraph testing is used in court in 19 states in America, subject to the discretion of the trial judge, but it is widely used by prosecutors, defence lawyers and law enforcement agencies across the US.
