Downing Street is not telling the truth about whether Boris Johnson was warned about alleged "predatory behaviour" by one of his Tory ministers, a former top civil servant has said.
Lord McDonald, who ran the foreign office at the time the complaint was made against Chris Pincher, said No 10 "keep changing their story and are still not telling the truth".
Downing Street previously claimed the prime minister was not aware of any specific allegations when he appointed Mr Pincher to be his deputy chief whip, and that “that it was deemed not appropriate to stop an appointment simply because of unsubstantiated allegations”.
But the ex permanent secretary, who was in charge at the time complaints were made about Mr Pincher in summer 2019, said it was "not true" that Mr Johnson was not aware of the specifics.
"Mr Johnson was briefed in person about the initiative and outcome of the investigation. There was a 'formal complaint',” the former head of the diplomatic service said in a letter to Katherine Stone, the parliamentary standards commissioner.
"Allegations were 'resolved' only in the sense that the investigation was completed. Mr Pincher was not exonerated. To characterise the allegations as 'unsubstantiated' is therefore wrong."
Lord McDonald, who is now a crossbench peer, in his letter to the standards commissioner that he was "aware that is unusual to write to you and simultaneously publicise the letter".
"I am conscious of the duty owed to the target of an investigation but I act out of of my duty towards the victims," he said, claiming that "Mr Pincher deceived me and others in 2019".
Speaking in BBC Radio 4’s Today programme after the release of his letter, he said: “I think they need to come clean. I think that the language is ambiguous. It's sort of telling the truth and crossing your fingers at the same time and hoping that people are not too forensic in their subsequent questioning. And I think that is not working.”
He added: “I dispute the use of the word ‘resolved’. For me ‘resolved’ is too positive a word. It sounds as though a happy and agreed conclusion was reached. No, the complaint was upheld. So to leave the impression that in some way Mr Pincher was exonerated is wrong.”
Asked why he had intervened publicly, he said: “First of all, Number 10 have had five full days to get the story correct, and that has still not happened. And second, I do not approve of anonymous briefings behind the scenes. If I was to do this, I should put my name to it rather than just phone a journalist and tip them off.”
The scrutiny of what the prime minister and other top Tories knew comes after Mr Pincher resigned his senior government job and lost the Tory whip after allegations that he groped two men in a private members’ club.
The MP, who is yet to resign his seat in the Commons, said he "drank far too much" and "embarrassed myself and other people".
The deputy prime minister Dominic Raab on Tuesday morning admitted letting Mr Pincher off with a warning after the earlier complaint.
Mr Raab, who was foreign secretary at the time said the minister was told he should "desist" from his alleged behaviour.
"There was a complaint made by someone that worked with him about inappropriate behaviour. I swiftly agreed with the permanent secretary Simon McDonald at the time, that that ought to be reviewed under the civil service's auspices to make sure it was done without fear or favour.
"It came back and did not recommend formal disciplinary action. And it should be said that the individual who made the complaint that did not want that. I spoke to Chris Pincher about the inappropriate behaviour, made it clear in no uncertain terms it should desist, it must never be repeated. So did the permanent secretary. For additional assurance, because I take this so seriously.
"I also referred it to the Cabinet Office propriety and ethics team which also looked at it for example, to see whether action were warranted under the ministerial code. They didn't, they agreed that it didn't warrant that.
"So although there was a complaint made about inappropriate behaviour, it did not trigger the disciplinary action either at the civil service level, or the cabinet office level in relation to the code of conduct.
"So I not only followed it to the strict letter, I went beyond that and sought the assurance. Why? Because I think it's so important that people that make complaints feel can have the confidence to come forward."
Reacting to Lord McDonald’s comments, Angela Rayner, Labour's deputy leader said it was clear the prime minister had “lied”.
“Boris Johnson’s desperate attempts to cover up what he knew about sexual assault complaints against Chris Pincher before appointing him have been blown out the water,” she said.
“It is now clear that the Prime Minister knew about the seriousness of these complaints but decided to promote this man to a senior position in government anyway. He refused to act and then lied about what he knew.
“Boris Johnson is dragging British democracy through the muck. His appalling judgement has made Westminster a less safe place to work.“
