He added: “There was no allegation made on the call. Alison never said to me, ‘we suspect she could be deliberately harming babies’.
“Had she said that it would have set off all sorts of alarm bells and we probably would have said, even with a lack of evidence, we would have recommended a referral at the time so we could contact the police.
“The key aspect of the Nursing and Midwifery Council is to protect the public but in order to do that we need clear information and evidence to restrict someone’s practice.”
Letby is serving 15 whole-life terms after being convicted of murdering seven babies and attempting to kill seven others, between June 2015 and June 2016, with two attempts on one of her victims.
After her convictions, Letby, 34, originally from Hereford, was stripped of her nursing credentials and struck off the register at an NMC fitness to practise hearing in December 2023.
The inquiry will resume in January when it will hear its final two weeks of evidence, with findings expected to be published in autumn 2025.
