David Davis says Cheshire police made ‘egregious’ failures in Lucy Letby investigation

Conservative former cabinet minister says nurse convicted of murdering seven babies has suffered a miscarriage of justice

The police force which conducted the investigation into the nurse Lucy Letby made “egregious” failures and did not follow official guidance or best professional practice, David Davis has said in parliament.

Speaking in the final parliamentary debate before the Easter recess, the Conservative former cabinet minister made a series of criticisms of Cheshire police and said Letby has suffered a miscarriage of justice. Davis said Cheshire police failed to appoint appropriate medical and statistics experts, and pursue all possible lines of inquiry into why babies died and collapsed on the “failing” neonatal unit of the Countess of Chester hospital in 2015-16.
