Boris Johnson is expected to face pressure other how truthful he has been about an alleged rule-breaking lockdown Christmas party in No 10 last year.

The Prime Minister will face PMQs on Wednesday after leaked footage showed his aides joking about a festive gathering on Tuesday night.

Downing Street Christmas Party – what we know so far

Questions have been asked about an alleged party at Downing Street last year on December 18.

Ministers are yet to explain how the alleged bash complied with the rules in place at the time, despite coming under pressure since an initial report in the Daily Mirror.

The newspaper said two events took place in No 10 in the run-up to the festive season last year, including Mr Johnson giving a speech at a leaving do during November’s lockdown.

The other was said to be a staff party in December where party games were played, food and drinks were served, and revelries went on past midnight.

At the time, the Tier 3 rules explicitly banned work Christmas lunches and parties where it is “a primarily social activity and is not otherwise permitted”.

Video shows Downing Street staff joking about ‘Downing Street Christmas party’

In footage obtained by ITV News, the Prime Minister’s then press secretary Allegra Stratton and adviser Ed Oldfield, along with other aides, were filmed joking about a “fictional” Downing Street party in December 2020.

Ms Stratton is seen answering questions at a mock press conference on December 22 about a party the previous Friday – the date of the alleged Covid rule-breaking gathering which is said to have been attended by dozens of colleagues while social mixing indoors was banned in London under Tier 3 restrictions.

Mr Oldfield can be heard asking Ms Stratton: “I’ve just seen reports on Twitter that there was a Downing Street Christmas party on Friday night, do you recognise those reports?”

Ms Stratton replied “I went home” before appearing to consider what the correct answer should be.

During the rehearsal, filmed as part of a subsequently-abandoned plan for Ms Stratton to lead televised press briefings, one aide is heard saying: “It wasn’t a party, it was cheese and wine.”

“Is cheese and wine all right? It was a business meeting,” Ms Stratton replied, to laughter in the room.

Ms Stratton then noted “this is recorded”, adding: “This fictional party was a business meeting … and it was not socially distanced.”
