Downing Street party: Boris Johnson pressure mounts as inquiry into Number 10 Christmas party to be widened to two other events

The probe into alleged Covid rule-busting parties in Government has been widened to include another festive celebration and a reported staff leaving do.

Cabinet Office minister Michael Ellis has told MPs that Cabinet Secretary Simon Case will, as well as investigating reports of a staff Christmas bash at Downing Street on December 18 2020, also look into two other alleged events.

He will include in his review a confirmed gathering at the Department for Education’s Whitehall headquarters on December 10 last year, and a reported leaving event for a No 10 aide on November 27.

The two December dates coincide with when mixing between households in London was restricted, with England in a month-long lockdown during November.

Both the Prime Minister and Health Secretary had suggested Mr Case could choose to extend his investigation – a move he has decided to make – beyond the main allegation that a Christmas party took place in Downing Street only 24 hours before the Government announced Christmas was cancelled,

The finding means that some claims, including that there was a party in Mr and Mrs Johnson’s No 11 flat on November 13 – the night the Prime Minister’s former chief aide Dominic Cummings departed – is not currently included in the scope of the review.

Answering an urgent question in the Commons, Mr Ellis said: “The primary purpose of the Cabinet Secretary’s investigation will be to establish swiftly a general understanding of the nature of the gatherings, including attendance, the setting and the purpose, and with reference to adherence to the guidance in place at the time.

“If required, the investigation will establish whether individual disciplinary action is warranted.”

The Paymaster General said that any evidence of potentially criminal behaviour “will be referred to the police and the Cabinet Office’s work may be paused”.

Ministers, special advisers and civil servants will be “expected to co-operate with this investigation”, said Mr Ellis, who added it would be for Mr Case to determine how long his inquiry lasts.

MPs were told the Cabinet Secretary was “not at any relevant gathering” included in the review.

Downing Street had refused on Wednesday to explicitly declare that Mr Case had not been at the December 18 event, where staff and aides are said to have drunk together, eaten cheese and swapped Secret Santa presents.

Fleur Anderson, Labour’s shadow Cabinet Office minister who asked the urgent question, called for the Government to “be straight with the British people” over what happened last year.

Conservatives also demanded answers over who had given reassurances to Boris Johnson that coronavirus regulations had been followed, with Kettering MP Philip Hollobone going so far as to suggest “possibly criminal” behaviour might have taken place.

Meanwhile, Health Secretary Sajid Javid said Mr Case had the authority required to “get to the bottom” of the claims being made and to “establish the facts”.

Mr Case’s inquiry was ordered by the Prime Minister after a leaked video emerged showing Downing Street aides laughing about a “fictional” party at No 10 in December 2020.

During interviews on Thursday, Mr Javid – who was not in Government at the time the parties are said to have taken place – repeated his past comment that he had been given assurances by senior officials that no Covid rules were broken last year.

But the Cabinet minister, speaking to LBC, said that if the rules had not been broken, then “a party could not take place”.

The leaked footage, obtained by ITV News, showed aides laughing about an alleged social event while rehearsing for subsequently ditched televised press briefings in No 10’s £2.6 million media room.

Allegra Stratton, a former spokeswoman for the Prime Minister who featured in the rehearsal, has since resigned while Ed Oldfield, a Downing Street media aide who is heard asking a practice question about a rumoured party, refused to answer questions when approached by Sky News.

After the video emerged on Tuesday evening, the Government opted not to put Mr Javid up for Wednesday’s morning broadcast interviews as initially planned, with the Health Secretary telling Sky he was upset by what he saw.

“It wasn’t about refusing (to go on air) – I spoke to my colleagues in No 10 and we actually agreed it is best to take some time to respond to the video in the way that the Prime Minister has now, by ordering an investigation by the Cabinet Secretary.”

Pressed on whether he thought an event did take place last December in Downing Street, he added: “The truth is, I don’t know.”

Following the saga of what went on in No 10, the Tories have come under further pressure after they confirmed that an event organised by Shaun Bailey’s failed London mayoral campaign took place in the party’s Westminster headquarters on December 14 while the capital was in tier 2 restrictions.

According to the Times, the “raucous” party took place in the HQ’s basement, was attended by No 10 aides and featured dancing and wine-drinking into the early hours despite indoor social mixing being banned at the time.

Four party staff members have been disciplined, the party said.

Meanwhile, Commons Leader Jacob Rees-Mogg has confirmed to MPs that the Commons is still scheduled to rise for Christmas on December 16, amid reports the recess could be brought forward in order to allow Mr Johnson to avoid next week’s final Prime Minister’s Questions before the festive break.
