A panel of international medical experts have argued Lucy Letby is innocent, citing “significant new evidence.” Letby, 35, is serving 15 life sentences for murdering seven babies and trying to kill seven more.

Her lawyers have asked the Criminal Cases Review Commission to investigate a possible miscarriage of justice. Ian Collins speaks with Mail On Sunday columnist, Peter Hitchens and reader in criminal law, Dr Hannah Quirk.
