The deputy prime minister, who was also the justice secretary, posted his resignation letter on Twitter.

It comes in the wake of the findings of the bullying report that Prime Minister tasked Adam Tolley KC with investigating eight formal complaints made against him.

The complaints related to Raab’s behaviour in three ministerial roles: justice secretary and foreign secretary under Boris Johnson, and Brexit secretary under Theresa May.

In his letter, he called the findings "flawed" and claimed they "set a dangerous precedent for the conduct of good government".

"I am writing to resign from your government, following receipt of the report arising from the inquiry conducted by Adam Tolley KC. I called for the inquiry and undertook to resign, if it made any finding of bullying whatsoever. I believe it is important to keep my word."

In another part of the letter, he wrote that he’s "genuinely sorry for any unintended stress or offence that any officials felt".

He also highlighted that the report concluded he had, "not once, in four and a half years, sworn or shouted at anyone, let alone thrown anything or otherwise physically intimidated anyone, nor intentionally sought to belittle anyone".

Rishi Sunak was presented with the findings of the report on Thursday.

Labour leader Sir Keir Starmer said the fact that he was allowed to resign shows the "weakness" of the Prime Minister.

Speaking at a hospital in North Yorkshire, Starmer said that Raab shouldn’t been allowed to resign and instead sacked.

"No matter how many times you change the person at the top", he said, the Conservatives "just can’t deliver", according to the BBC.

Raab was reappointed by Sunak after he took power in October, a move which Starmer said should never have happened.

The bullying allegations first emerged in November when the Guardian spoke to numerous sources at the MoJ who claimed Raab had been "demeaning" to civil servants, and "very rude and aggressive".

They said he created a "culture of fear" and "wasn’t just unprofessional, he was a bully", the publication said. 

The sources claimed that 15 senior civil servants in his private office were offered "respite or a route out" due to concerns some were still traumatised from his previous tenure.

The same month, Sir Gavin Williamson resigned after allegations of bullying.

The MP was accused of sending abusive messages to a fellow MP and of bullying a senior civil servant during his time as defence secretary.
