A former MoD official told the Guardian that Sir Gavin also told them to “jump out of the window” in what they felt was a sustained campaign of intimidation. But in a statement, Sir Gavin said: “I categorically reject this allegation and have a good working relationship with the many brilliant officials I have worked with across government. “No specific allegations were ever brought to my attention.” Live policy updates: Sunak backs Williamson despite ‘unacceptable’ texts The Cabinet minister is currently facing allegations that he sent abusive messages to former leader Wendy Morton, complaining that he and other colleagues had been excluded from the Queen’s funeral for political reasons. But while Prime Minister Rishi Sunak has condemned the language as “unacceptable”, he said it was “right” to investigate complaints “before decisions are made about the future”. And his official spokesman said earlier that the prime minister has full confidence in him. According to the Guardian, the civil servant, who later left the government, said Sir Gavin “deliberately humiliates and intimidates them” on a regular basis. While they reported the incidents informally to the Foreign Office’s head of human resources, they decided not to make a formal complaint. But they said a senior military aide working in the department later apologized to them for not flagging his behavior. A Cabinet Office spokesman said: “The Cabinet Office has not been made aware of any formal complaints about Gavin Williamson’s conduct from his time at the Ministry of Defense or any other department.” Sir Gavin served as Defense Secretary from November 2017 to May 2019, but was sacked by then Prime Minister Theresa May amid controversy over a government leak. He was rehired by Boris Johnson as education secretary two months later, but was sacked again in September 2021 after much criticism over his handling of the pension during the COVID pandemic. Mr. Sunak brought him back into government two weeks ago to serve as a Cabinet minister, who also attends the cabinet.
