Sources said the doctor, in his 50s, later moved to work at a different hospital. He had been ill before his death last month. His funeral has been held. He applied for anonymity for Letby’s ten-month trial to protect his family, and was granted the order. He was called Doctor A in court. Prosecutors referred to him as Letby’s “boyfriend”, and said she was infatuated with him — alleging she created “crisis situations” by attacking babies knowing he would be bleeped and run to attend. It was revealed they went on day trips to London, met for walks and meals. Most read in The Sun Letby denied being in love and said they were trusted friends. But she called him “sweetie” in messages and cried when he entered the dock at Manchester crown court. In messages between them, the doctor told Letby she was “one of the few nurses I would trust with my own children”, the court heard. At 2024’s Thirlwall Inquiry the doctor said he had been “misled” and “maybe manipulated” by Letby. He said he had been tricked by her into giving her information about babies she had attacked. Letby was found guilty of murdering seven babies and attempting to kill seven more at the Countess of Chester Hospital. She is serving a whole-life order at Bronzefield Prison, Surrey, but maintains her innocence. The Criminal Cases Review Commission is considering evidence presented by a panel of doctors claiming that natural causes and poor care were to blame.
