No hard evidence against Lucy Letby’ senior Tory claims as he calls for retrial - Sir David Davis said there was no ‘hard evidence’ implicating Letby and the case against her was ‘built on a poor understanding of probabilities’.

Lucy Letby should face a retrial, Sir David Davis has told Parliament, as he claimed the NHS was “most likely” responsible for baby deaths at her hospital.

Sir David claimed "erroneous" statistical evidence against Letby was even worse than the ultimately discredited data used against Cheshire solicitor Sally Clark, whose conviction for murdering her two sons was overturned in 2003.

Sir David says the former nurse's conviction was "built on a poor understanding of probabilities" and lacked "hard evidence".
