Ms Kelly tells the inquiry she didn't alert police sooner as there was "no actual evidence as in nobody had seen her do anything" and that she hadn't regarded the rise in baby deaths as a safeguarding issue.

"There was terms used like 'gut feeling' and 'drawer of doom' which didn't pinpoint any issues to do with Letby, so on the basis of that, I didn’t have any facts or evidence that I could base my decisions on.

Alison Kelly was director of nursing at the Countess of Chester Hospital during the period when Lucy Letby attacked babies on the neonatal unit.
