Gavin Williamson dramatically quit Rishi Sunak’s cabinet last night after the Guardian revealed claims that he told a senior civil servant they should “slit your throat” while he was defence secretary.

The Cabinet Office minister stepped down after the former Whitehall aide put in a formal complaint to parliament’s independent complaints and grievance scheme (ICGS), piling more pressure on Sunak over his decision to reappoint his ally.

Williamson’s fate appeared to be sealed after further bullying allegations from his former deputy chief whip, who criticised his “unethical and immoral” behaviour and claimed he used “leverage” and threats to control MPs and instil a culture of fear in Westminster.

In his resignation letter, Williamson conceded that claims about his conduct had become a “distraction” and said he had decided to “step back from government” while the complaints process was carried out, vowing to “clear my name of any wrongdoing”.

In his response, Sunak said he was accepting Williamson’s resignation with “great sadness” but added that he supported his decision to stand down. Sunak also thanked his political ally for his “personal support and loyalty” and the work he had done during his brief spell in government.

His decision to quit – the third time he has been forced to leave cabinet – follows allegations that he sent expletive-laden messages to the former chief whip Wendy Morton complaining about not being invited to the Queen’s funeral.
