Child serial killer Lucy Letby is planning to launch a fresh appeal with a new legal team, her barrister has said, according to the BBC.

The former nurse was convicted of the murders of seven babies and the attempted murders of seven others, with two attempts on one child, when she worked on the neonatal unit at the Countess of Chester Hospital between June 2015 and June 2016.

After two trials, Letby is serving 15 whole-life orders – making her only the fourth woman in UK history to be told she will never be released from prison.

In May, Letby lost her Court of Appeal bid to challenge her convictions from last year, following an initial appeal rejection in January.

The BBC reported that Letby has now changed her legal team, which was led by Benjamin Myers KC, who is shortlisted as the Criminal and Extradition Silk of the Year in the Legal 500 Awards 2024.

The BBC added her new barrister, Mark McDonald, told Radio 4’s File On 4 programme that he plans to make an application to the Criminal Cases Review Commission (CCRC) for Letby’s case to be sent back to the Court of Appeal.

“I knew almost from the start, following this trial, that there is a strong case that she is innocent,” he told the programme.

“The fact is juries get it wrong. And yes, so do the Court of Appeal, history teaches us that.”

Mr McDonald will be taking Letby's case on a pro bono basis.

The CCRC is an independent body and last year received more than 1,600 applications for reviews against convictions and/or sentences.

Since starting work in 1997, the CCRC has referred around three per cent of applications to the appeal courts.

Mr McDonald has repeatedly applied to the CCRC for clients Michael Stone, serving three life sentences for the murders of Lin Russell and her daughter Megan, and the attempted murder of Lin Russell's other daughter Josie, and Benjamin Geen, a nurse jailed for life for murdering two patients and poisoning 15 more.

A public inquiry examining events at the Countess of Chester Hospital following Letby’s multiple convictions is due to begin on Tuesday, September 10 in Liverpool.
