The trial of Lucy Letby was chilling but, alongside the horror at her crimes and the heartbreak of hearing of what the victim’s parents had been through, was astonishment. Not just that someone who was supposed to care for helpless babies on a neonatal unit could take so many lives, but that she had not been stopped sooner.
North of England correspondent Josh Halliday has spent most of the last year covering the trial and talking to those involved in it. He spoke to whistleblowing medics who were not just ignored, but treated as troublemakers for trying to ensure she was investigated. And he heard how the advice of two reviews – that forensic investigations should be launched – were not followed. He also tells Nosheen Iqbal about the measures the government is taking to ensure that such a terrible case is never repeated.
