Lucy Letby’s life behind bars is made up of watching DVDs in her cell alone and serving fellow prisoners in the jail’s canteen, a former inmate has claimed.

The serial child killer is serving 15 whole life sentences after she was found guilty of murdering seven babies and attempting to murder seven others during her time as a neonatal nurse at the Countess of Chester hospital in Chester.

She will spend the rest of her life behind bars, and is currently locked up in HMP Bronzefield, where former inmates told she spends her time quietly working and trading DVDs with other prisoners.

They claimed she has been working in the prison’s canteen as a server in the block housing the most high-profile prisoners, including Sara Sharif’s stepmother Beinash Batool. Prisoners in the block are given rooms with their own private bathrooms, and other personal privileges, the former inmate added.

The source also said Letby keeps to herself and avoids social events including talent shows put on by the inmates, instead choosing to binge watch reality TV show Four in a Bed on her Freeview TV.

“She has to stay on her wing, and be with staff all the time,” they said. “Everyone knows who she is in there.”

Of the unit she is housed in, the source said: “A lot of people don’t want to go over there because that’s where the high profile killers are.”

They continued: “I’ve seen her around when I’ve been over there and said hello, but she’s quiet and keeps to herself.”

It comes as the Criminal Cases Review Commission (CCRC), which investigates potential miscarriages of justice, considers an application by Letby’s legal team to send the case back to the Court of Appeal.

Because two previous attempts to challenge Letby’s convictions have been unsuccessful, Letby’s legal team can no longer challenge her convictions at the Court of Appeal without significant new evidence that was not available during her first trial.

But evidence used to convict the killer nurse has been challenged by Canadian professor Dr Shoo Lee who convened a panel of experts in London for a press conference last year. He claimed there was no medical evidence to support the convictions and suggested the deaths and injuries were caused by natural causes or "bad medical care".

Last year, A CCRC spokesperson said: “It is for the CCRC to find, investigate and if appropriate, refer potential miscarriages of justice to the appellate courts when new evidence or new argument means there is a real possibility that a conviction will not be upheld, or a sentence reduced.

"At this stage it is not possible to determine how long it will take to review this application. A significant volume of complicated evidence was presented to the court in Ms Letby's trials.

"The CCRC is independent. We do not work for the government, courts, police, the prosecution or for anyone applying for a review of their case. This helps us investigate alleged miscarriages of justice impartially."
