Lucy Letby’s lawyers have said they will be asking the Court of Appeal to immediately review all of her convictions because an expert witness “has now changed his mind on the cause of death of three babies”.
The former nurse is serving 15 whole-life jail terms for murdering seven babies and trying to kill seven others while working as a neo-natal nurse at the Countess of Chester Hospital.
Her barrister Mark McDonald told a news conference in London that the lead prosecution expert, Dr Dewi Evans, had altered his view about how the babies died.
He said: “Remarkably, Dr Evans has now changed his mind on the cause of death of three of the babies: Baby C, Baby I and Baby P.”
Letby was convicted in August 2023 and has twice previously been refused permission to appeal against her convictions.
Speaking at London’s Royal Society of Medicine, Mr McDonald said: “The primary grounds of appeal at the previous hearings related to the admissibility before the jury of the evidence of the lead prosecution expert Dr Dewi Evans.
“The defence argued twice at trial that Dr Evans’ evidence should be disregarded. This was refused by the trial judge.
“It was then later argued in the Court of Appeal, and was refused in the court of appeal.”
He said that “remarkably” Dr Dewi Evans had changed his mind over the mechanism of death involving three babies.
“The defence will argue that Dr Evans is not a reliable expert, and all the convictions are not safe,” he said.
The nurse, 34, originally from Hereford, was convicted of the murders and attempted murders while working at the hospital between 2015 and 2016.
She made two attempts to kill one of her victims.
