Lucy Letby has replaced her legal team in a bid to overturn the convictions for which she is currently serving a whole life sentence,
The former neonatal nurse has no prospect of parole after being convicted of the murders of seven babies and the attempted murder of seven others at Countess of Chester Hospital.
Mark McDonald, a specialist barrister in appeals and miscarriages of justice, told the BBC that he was now representing Letby.
Mr McDonald said he plans to take her case to the Criminal Cases Review Commission (CCRC) to apply for it to be sent back to the Court of Appeal.
The specialist barrister would need to secure fresh evidence and persuade the CCRC that such evidence undermines the safety of her convictions.
He said: “I knew almost from the start, following this trial, that there is a strong case that she is innocent. The fact is juries get it wrong. And yes, so does the Court of Appeal, history teaches us that.”
On Wednesday, he posted on X: “The day after Lucy was convicted I raised concerns. I was attacked for speaking out even reported to my professional body.
“There are many hurdles to overcome in coming years but one day justice will be done and those wrongly convicted will be freed.”
