Lucy Letby's lawyers say expert witness has 'changed his mind' on cause of death of three babies

Lucy Letby's legal team has said the lead prosecution expert has "now changed his mind" on the cause of death of three babies, meaning all of her convictions should be reviewed.

Her new lawyer Mark McDonald said Dr Dewi Evans had told the jury Letby had injected air down a nasal gastric tube, leading to the death of the three babies.

But he said Dr Evans had now "changed his mind on the cause of death of three of the babies", leading Letby's lawyers to seek permission from the Court of Appeal to reopen her appeal and immediately review all her convictions.

Letby is serving 15 whole life terms in prison for the murder of seven babies and the attempted murder of seven others while working at the Countess of Chester Hospital in 2015 and 2016.

There is an ongoing public inquiry into how Letby was able to kill and carry on killing at the hospital.

Police are also continuing their investigation into Letby and the care of hundreds of other babies she looked after during her career.

Detectives have confirmed they interviewed the former nurse under caution in prison over more deaths and incidents in Chester and also at Liverpool Women's Hospital, where she spent time on placement in 2012 and early 2015.
