Rishi Sunak was unaware of “any specific allegations” against Gavin Williamson, a No 10 ally has said, as the prime minister faces further scrutiny over his judgment in bringing him back to the cabinet.
Williamson resigned as a Cabinet Office minister on Tuesday after the Guardian revealed claims that while he was defence secretary he told a former senior civil servant to “slit your throat”. It followed allegations he sent expletive-laden messages to the former conservative chief whip Wendy Morton complaining about not being invited to the Queen’s funeral.
