POLICE are reviewing whether a Christmas quiz at No 10 may have breached coronavirus restrictions after a picture emerged showing Boris Johnson and colleagues near an open bottle of sparkling wine.

Scotland Yard said yesterday that officers were reconsidering their previous assessment that the event on December 15, 2020 did not meet the threshold for criminal investigation after the new evidence emerged.

The Mirror published a photo showing the Prime Minister and three members of staff – one wearing tinsel and another in a Santa hat – near what appears to be an uncorked bottle of prosecco and an open bag of crisps.

Downing Street insists the event was a “virtual quiz” and police had decided not to investigate it alongside 12 other events after being passed evidence from the Sue Gray inquiry into alleged lockdown breaches.

But the Metropolitan Police said in a statement yesterday: “The MPS previously assessed this event and determined that on the basis of the evidence available at that time, it did not meet the threshold for criminal investigation. That assessment is now being reviewed.”

The development suggests the latest image to surface was not among more than 300 passed to officers by the Whitehall investigation, and adds to the pressure on Johnson after major Tory donor John Armitage suggested his leadership is past the point of no return.

The Met are also said to be preparing to interview more than 50 people who attended Downing Street ­parties, including the Prime Minister.

Battling to stay in power in the face of Conservative unrest over ­partygate, Johnson signalled to the Commons that laws requiring people in England with Covid-19 to ­self-isolate will be lifted within weeks.

But the Mirror publishing its ­latest photo during Prime Minister’s Questions prompted a challenge from shadow minister Fabian Hamilton.

The Labour MP said the ­image ­appears to show “one of the ­Christmas parties he told us never happened”, adding: “Will the Prime Minister be referring this party to the police as it is not one of the ones currently being investigated?”

Johnson responded: “In what he has just said, I’m afraid he is completely in error.”

Challenged again during PMQs, Johnson added: “That event already has been submitted for investigation.”

Tory MP Neil Hudson called for all the evidence to be published to stem the “drip, drip, drip” of ­alleged Covid breaches and “upsetting ­images”, in a sign the revelation was further damaging Conservatives’ view of Johnson.

“I’m incredibly disappointed and upset. Yet again I have to say that ­categorically I will not defend the ­indefensible,” the Penrith and The Border MP told GB News.

“I’m very clear that if rules have been broken, and indeed if the law has been broken, it doesn’t matter how serious you are, there has to be serious consequences.”

London was under Tier 2 ­restrictions at the time, which ­prohibited social mixing between ­different households indoors.

Official guidance said: “Although there are exemptions for work ­purposes, you must not have a work Christmas lunch or party, where that is a primarily social activity and is not otherwise permitted by the rules in your tier.”

Gray’s update on her inquiry ­revealed that police were ­investigating 12 events in Downing Street and wider government, but the “online Christmas quiz” was not considered to have “reached the threshold for criminal investigation”.

The National: LONDON, ENGLAND - JANUARY 24: Dominic Cummings, former advisor to Prime Minister Boris Johnson, poses for photographers outside his home on January 24, 2022 in London, England. Sue Gray, a civil servant who is a permanent secretary at the Cabinet Office,

Dominic Cummings (above), Johnson’s hostile former chief adviser, tweeted “there’s waaaaay better pics than that floating around”, including of inside the Prime Minister’s official ­Downing Street flat.

A separate image of the same quiz emerged in December but did not show any alcohol.

Adam Wagner, a human rights ­lawyer who has been examining ­Covid laws, said it “seems obvious” from the new photo that Johnson is “participating in a social gathering”.

The Prime Minister’s press ­secretary insisted the event was a “virtual quiz” but was unable to say whether the photograph had been submitted to the Gray inquiry.

“I’m not going to get into precise evidence but she obviously had access to all the evidence she needed,” the press secretary said.
