The government will ask the Parole Board to look again at its decision to release a double child killer who was the first murderer to be convicted using DNA evidence.

Colin Pitchfork was jailed for life in 1988 for raping and murdering 15-year-olds Lynda Mann and Dawn Ashworth.

Earlier this month the Parole Board said it was satisfied Pitchfork was safe for release.

But the justice secretary is to apply to the board to reconsider.

Robert Buckland will write to the Parole Board on Monday, arguing that the decision to release the 61-year-old is irrational.

A Ministry of Justice spokesperson said: “Our heartfelt sympathies remain with the families of Lynda Mann and Dawn Ashworth.

“After a careful review, the Lord Chancellor will ask the Parole Board to reconsider its decision.”

Under rules passed by Parliament to ensure judicial independence from politicians, ministers cannot block Pitchfork’s release, or directly order the Parole Board to retake the decision.

Instead, they have 21 days to make submissions to the board as to why a panel’s decision is arguably wrong.

Pitchfork, who was in his 20s at the time of the attacks, left his baby son sleeping in the back of his car and raped and strangled Lynda Mann in November 1983.

Three years later, less than a mile from where Lynda died, he raped and murdered Dawn Ashworth.

A police investigation initially led to the wrong man, a 17-year-old who falsely confessed to one of the killings.

After an unprecedented mass screening of 5,000 men using pioneering “DNA profiling” technology, Pitchfork was eventually caught and given a life sentence in January 1988.

Pitchfork has spent 33 years in prison and was previously denied parole in 2018.

But on 7 June, the Parole Board said it was satisfied Pitchfork was suitable for release, subject to conditions.

The panel considered more than 1,100 pages of information, victim statements and heard evidence from Pitchfork, as well as his probation officers, police and a psychologist.

When Pitchfork was jailed in 1988, the then home secretary still had the power to order that he never be released.

The Lord Chief Justice of the time advised that the killer may never be safe to be let out – but the minister decided on a 30-year minimum term.

Since then, governments have successfully removed themselves from decisions about managing offenders to comply with wider legal concerns that the criminal justice system should be independent of the prevailing winds of politics.

So today, ministers cannot directly order the Parole Board to retake a decision – Justice Secretary Robert Buckland can only hope that the judge who is asked to look at Pitchfork’s papers agrees that the decision was so irrational on the evidence that it needs to be taken again.

The way the law works and the statistics show that very few Parole Board decisions – whether to keep someone inside or to let them out – are changed following this reconsideration process.

There have been at least 240 applications from prisoners for their parole refusals to be reconsidered in the last three years – and only 15 were returned for a new hearing.

The secretary of state has made about 32 submissions to keep someone inside. Only eight went to a full reconsideration – and only one of those led to the inmate remaining behind bars for longer.

Alberto Costa, Conservative MP for South Leicestershire, has campaigned for Pitchfork to remain behind bars and thanked the Lord Chancellor for his intervention.

He said: “The national outrage following the Parole Board’s decision a few weeks ago is proof that many people remain haunted by Pitchfork’s abhorrent and heinous crimes.

“The Parole Board now has a final opportunity to get it right.”

Mr Buckland will formally ask the board to re-examine the decision, under the provisions of the so-called reconsideration mechanism, introduced in July 2019.

This allows people to challenge the board’s decision if they believe them to be “procedurally unfair” or “irrational”.

However, the provisions make clear that “being unhappy with the decision is not grounds for reconsideration”.

It is understood the Parole Board will comment on the next steps in the process once the justice secretary’s formal application has been received.
