The legal team of killer nurse Lucy Letby has claimed that "new evidence" has undermined her murder convictions, calling for an immediate review into the convictions.

This demand has come has an expert witness "has now changed him mind of the cause of death of three babies".

The disgraced nurse is currently serving a whole-life sentence for the murder of seven babies and attempting to kill seven more while she worked as a neo-natal nurse at the Countess of Chester Hospital.

She had been convicted in August 2023 and was also refused permission to appeal against the convictions the following year in May 2024.

Lucy Letby had been sentenced to life in prison last yearPA

Speaking at a press conference in London today, lawyer Mark 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.

“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.”
