Letby was later found guilty of the attempted murder of a seventh baby at a retrial in 2024.

Her attempts to appeal her convictions have failed. 

However, there is a groundswell of support for her with some people – including a Sark based medico-legal expert – calling for her case to be looked at again.

Yesterday, senior Conservative MP, Sir David Davis called for a retrial of the convicted serial killer in a speech to the UK’s House of Commons.

Sir David said he had originally been convinced of the former neonatal nurse’s guilt, but has changed his mind and now believes “there was no hard evidence against Letby” and that “nobody saw her do anything untoward”.

Sir David said Letby’s conviction had been based on a series of coincidences, including the fact that she was working when some of the babies had died.

He called in to question the prosecution evidence given by Consultant Paediatrician Dr Dewi Evans, and referenced Dr Bohin and the complaints raised against her locally.

“Questions have also been raised about the second expert witness for the prosecution, Dr Sandie Bohin,” he said.

“Eight families are currently filing formal complaints against her over their children’s care, which are being considered by the General Medical Council.” 

Sir David told the House of Commons, “There is a case in justice, in my view, for a retrial.”

He said there is a problem that “much of the evidence was available at the time” but was “simply not presented to the jury”.
