Aides to Boris Johnson reportedly had sex at a raucous Downing Street party the night before Prince Philip's funeral.
New allegations have emerged about the April 2021 bash where staff brought a “suitcase of wine” and broke a swing belonging to the PM’s son.
According to an ITV News podcast, at least two couples were seen “getting it on with each other” and “touching each other up” at the bash, which Boris Johnson did not attend.
Two members of staff were said to have been “all over each other” in a kitchen area during the party, which went past 4am.
Now The Times has reported some aides were believed to have had sex.
According to the newspaper, “numerous witnesses” saw two couples becoming intimate with each other at the gathering.
One pair were seen "feeling each other up" in a kitchen, then went to a dark room from which they later emerged "flustered”, the newspaper reported. The other pair went into an office "with the lights off".
Social gatherings indoors were still banned at the time for people from different households or bubbles.
A No10 spokesman did not deny the romp claims, but said: “As we’ve talked about, there was the investigation into those incidents, which was reported and also looked into by the Met Police.
“At all times staff were given clear guidance to retain any relevant information and co-operate.”
It comes after claims staff “shredded things” before an investigation into lockdown-busting bashes.
Labour asked “what did they have to hide?” after a No10 whistleblower said evidence was “destroyed” ahead of a Whitehall probe.
Ethics chief Sue Gray found “failures of leadership and judgement” in No10 and the Cabinet Office, while police issued 126 fines - including one to Mr Johnson.
But a new podcast claimed only half the rule-breaking parties were ever investigated by Ms Gray or the Met Police.
A source told ITV’s Partygate: The Inside Story: “There was a sense, and an implication, that we should start deleting evidence before there is an investigation.
“And a lot of people started shredding things. Any proof of the events started disappearing.”
Tom Brake, director of Unlock Democracy, said: "There can be no excuse for shredding documents and only one explanation - there is something damning to hide and evidence is being deliberately destroyed."
Deputy Labour leader Angela Rayner said: “The bombshell claim that crucial documents were put through the shredder ahead of the Partygate investigation are very serious indeed.
“The suggestion key evidence was systematically deleted implies an organised cover-up right from the top.
“The disgraced former Prime Minister now has serious questions to answer about his own involvement in this apparent withholding of evidence and Rishi Sunak must come clean on exactly what he knew.
“What did they have to hide?”
A source close to Mr Johnson said staff were repeatedly told not to destroy or conceal any information
But the claims pile pressure on the ex-PM - weeks before public hearings could finally begin into whether he misled MPs over the scandal.
The Privileges Committee is investigating if Mr Johnson’s denials were contempt of Parliament.
The seven-strong team of MPs met yesterday to sift through evidence. It is thought they have still not set dates for hearings but members hope to start within weeks, and plan to grill Mr Johnson in public.
If he is found in contempt he could be suspended or even face a by-election - scuppering allies’ hopes of a sensational No10 comeback.
