The former chairman of the hospital where serial killer Lucy Letby murdered babies has said his decision to not invite the doctors who suspected her to an important meeting was "a big personal failure".
Sir Duncan Nichol chaired the board of directors at the Countess of Chester Hospital at the time Letby killed seven infants and tried to kill seven others between June 2015 and June 2016.
He also described an "emotional meeting" with one of those doctors after the police investigation began where he had apologised for not intervening sooner.
Sir Duncan has spoken publicly about the case for the first time at the public inquiry into the circumstances around Letby's offending and the NHS response.
