Thephotographs, obtained by ITV News, were taken at a gathering in honour ofDowning Street"s outgoing director of communications Lee Cain in November 2020,an event previously investigated by police for potential breaches of the law.
Monday"sphotographs show Johnson making a speech and raising a toast, with half a glassin his hands, ITV said.
At thattime, large gatherings with people outside of your own household were bannedafter England had been put back into a national lockdown due to rising cases ofCOVID-19.
Reuterscould not independently verify when or where the pictures were taken. Johnson"soffice has said police had access to all information during theirinvestigation, including photos.
Johnson wasnot fined for taking part in the November 2020 event, though he was issued witha fixed penalty notice for a Downing Street gathering to mark his birthday inJune that year, an event which he said lasted no more than 10 minutes.
He hasapologised for what he called a mistake but refused to resign over the issue.
TheMetropolitan police referred to a statement announcing the end of itsinvestigations last week when asked if it had been aware of the Cain leavingparty pictures during its investigation.
The CabinetOffice, which has been handling a separate government investigation into theparties, declined to comment.
Thegovernment is expected this week to publish a long-awaited report by the seniorcivil servant Sue Gray into the events held at Johnson"s Downing Street officeduring coronavirus lockdowns. Police have handed out 126 fines in connectionwith the parties.
The report,which is expected to include details of some events that were not investigatedby the police, could spur more criticism of the British leader, who has beenunder months of pressure over several scandals and U-turns.
The newphotos appear to undermine some of Johnson"s previous statements. When asked inparliament in December about reports of a party at his residence the previousmonth, Johnson said that he was sure "the rules were followed at alltimes".
AngelaRayner, the opposition Labour Party"s deputy leader, accused Johnson of lying.
"BorisJohnson said repeatedly that he knew nothing about law-breaking – there’s nodoubt now, he lied," Rayner said. "Johnson made the rules, and thenbroke them."
