LUCY Letby’s lawyers are set to reveal new evidence which “significantly undermines” her conviction for murdering seven babies.
Barrister Mark McDonald, representing the killer nurse, said he would be giving “fresh developments” in the case.
He is due to make an announcement on Monday afternoon at the Royal Society of Medicine in London.
Letby, 34, is currently serving 15 whole life terms for murdering seven babies and attempting to kill six who were in her care at the Countess of Chester Hospital.
During a retrial this summer, she was convicted of a seventh attempted murder.
Her killing spree spanned from June 2015 to June 2016.
Mr McDonald said of the developments: “There will be a press conference by the legal defence team for Lucy Letby to announce fresh developments on the case.
“At the conference we will also be announcing new evidence, which significantly undermines the convictions.”
He added more than 50 experts, covering neonatology, pathology and statistics, are willing to help challenge Letby’s convictions.
It comes just weeks after the former neonatal nurse was questioned by cops over more baby deaths across two hospitals.
Detectives quizzed her over more death at Countess of Chester and cases at Liverpool Women’s Hospital, where she trained as a student.
It is believed this is the first time police interviewed Letby over deaths at the Liverpool hospital.
Police interviewed her at category A women’s prison HMP Bronzefield in Ashford, Surrey.
After she was first convicted at Manchester Crown Court last August, Cheshire Police began a review of all 4,000 babies she cared for during her time at both hospitals, dating back to January 2012.
In October, Letby was refused permission to appeal against her latest conviction for trying to murder a premature baby girl.
She tried to get approval to challenge the most recent conviction in July for the attempted murder of a baby girl following a retrial.
But three senior judges at the Court of Appeal refused to grant her permission to appeal.
On the latest investigation, Cheshire Police said: “We can confirm that, following agreement, Lucy Letby has recently been interviewed in prison under caution in relation to the ongoing investigation into baby deaths and non-fatal collapses at the Countess of Chester Hospital and the Liverpool Women’s Hospital.
“Further updates will follow at the appropriate time.”
