Main contribution

In April 2018, Cheshire Police approached Professor Jane Hutton of Warwick University and asked her to calculate the probability of one nurse being on duty for all the deaths and collapses under investigation. According to an account given by David Davis MP in the House of Commons on 8 January 2025, police signed a consultancy agreement with her before telling her in 2021 that prosecutors had instructed them not to pursue the statistical question further.

Key claim

Davis told MPs that Hutton advised police the question was wrongly framed: a proper statistical inquiry should not concentrate on one pre-identified staff member, but should investigate all possible explanations for the unit's collapses, including medical conditions, prematurity and the unit's broader performance, before focusing on an individual. He said the jury that convicted Letby was never told of this advice.
