THE ex-chairman of the NHS trust where serial killer Lucy Letby worked believes the board was “misled” by hospital executives, it emerged yesterday.

The nurse was convicted last week of murdering seven babies and trying to kill another six at the Countess of Chester Hospital in Cheshire.

Sir Duncan Nichol said the Countess of Chester Hospital NHS Foundation Trust was told that there was “no criminal activity pointing to any one individual” despite mounting concerns.
