Boris Johnson took a Christmas quiz between two colleagues at # 10 last year – while mixing interiors was banned in London.
The Sunday Mirror posted a picture of Mr Johnson at the event, which took place on December 15th.
Downing Street said the prime minister “took a short virtual quiz” to thank staff for their hard work during the pandemic.
Labor Angela Rayner said Mr Johnson was “unable to run this country”.
It comes after the government opened an investigation into three allegations of gatherings last year – including two on Downing Street – despite Covid rules banning them.
In the photo, Mr. Johnson is sitting in Library # 10 between a colleague who is wearing a tinsel scarf and another who appears to be wearing a Santa hat.
A source told the Sunday Mirror that many employees were huddled together by computers, conferring questions, drinking alcohol and having four teams of six in an office.
London at the time was subject to Tier 2 restrictions, which banned the mixing of households indoors – aside from support bubbles – and allowed a maximum of six people to meet outside.
The official guidelines state, “Although there are exceptions for work purposes, you may not have a Christmas dinner or party at work if it is a primarily social activity and is otherwise not permitted by the rules at your level.”
In response to the photo, a spokesman for No10 said, “This was a virtual quiz. Downing Street employees had to be in the office often to work on the pandemic response, so those who were in the office to work may have participated virtually from their desks. “
A Downing Street source told the BBC that the two people in the picture with Mr. Johnson were members of his close staff who had helped him with the technology.
But Labor vice chairwoman Ms. Rayner said, “Boris Johnson really believes it’s one rule for him and another for everyone else.
“Despite repeated rejections of parties in No. 10, it has now turned out that there were numerous parties, meetings and the prime minister even took part in a festive quiz,” she said.
The Ministry of Labor and Pensions has confirmed that some of its employees drank alcohol and ate snacks several times “late into the evening” during the Covid restrictions.
What follows is a report in the Sunday Mirror alleging that policy and officials working for Minister Therese Coffey often drank into the wee hours after work.
On Friday the 10th, Downing Street announced its 2021 Christmas party due to mounting anger over another gathering on the 18th.
Earlier this week, following criticism from opposition parties, the media and his own MPs, the Prime Minister asked Cabinet Secretary Simon Case to open an investigation into the party on December 18.
The investigation will also include finding out what happened at another meeting on Downing Street on November 27th last year and another at the Department of Education on December 10th.
Allegra Stratton resigned as government spokeswoman on Wednesday following a backlash to a video she appeared in last December joking about a Christmas party.
The Christmas party dispute escalated further when the UK government announced new rules to combat the spread of Omicron.
Mr Johnson is facing a rebellion of around 60 Conservative MPs when the measures are put to the vote in the House of Commons next week.
Government sources suggested that the introduction of Plan B
Action for England on Tuesday will be broken down into three separate votes, including one on Covid passports, which some Tories have rejected. However, the measures are expected to become law as Labor supports the government. Another 633 Omicron cases were reported on Saturday – but the actual number is estimated to be much higher. In total, a further 54,073 daily cases were recorded across the UK. Meanwhile, a report from the London School of Hygiene and Tropical Medicine suggests the UK will face a significant wave of Omicron infections in January with no further restrictions beyond Plan B. It also says the death toll between now and April could range between 25,000 and 75,000.
