Pressure mounts on Boris Johnson amid new claims of Downing Street parties held while the Queen mourned Prince Phillip

Pressure is mounting on Boris Johnson amid fresh allegations that two further Downing Street parties were held while coronavirus restrictions were in place, the night before the Duke of Edinburgh's funeral.

The events were held in April last year, while the country was in a period of national mourning, it was reported. The Prime Minister was said to have been away from Downing Street at the time.

The Queen attended the funeral of Philip, her husband of 74 years, wearing a face mark and socially distanced from her family at Windsor Castle in line with Covid restrictions.

Sir Ed Davey, the leader of the Liberal Democrats, said: "The Queen sitting alone, mourning the loss of her husband, was the defining image of lockdown. Not because she is the Queen, but because she was just another person, mourning alone like too many others.

"Whilst she mourned, Number 10 partied. Johnson must go."

His comments were echoed by Labour deputy leader Angela Rayner, who wrote on Twitter: "The Queen sat alone in mourning like so many did at the time with personal trauma & sacrifice to keep to the rules in the national interest.

"I have no words for the culture & behaviours at number 10 and the buck stops with the PM."

Fran Hall, from Covid-19 Bereaved Families for Justice, said: "If your neighbours had behaved like this, you'd have been disgusted. For the people running the country to do it and then lie about it, shows a complete disdain for the general public.

"We shared the same pain of grieving in isolation as the Queen did. And she must be just as sickened as we are at hearing this. Sadly, instead of doing the decent thing and resigning, we can expect the Prime Minister to continue shamefully lying to our faces.

"The Conservative MPs that are keeping him in power disgrace their country."

The news came as Andrew Bridgen, the Conservative MP for North West Leicestershire, became the fifth MP to publicly announce he had submitted a letter of no confidence in the Prime Minister on Thursday night.

Mr Bridgen told BBC Newsnight: "With a heavy heart, I have written a letter to Sir Graham Brady indicating that I have no confidence in the Prime Minister and calling for a leadership election."

The Telegraph reported that as many as 30 letters have been submitted so far. A total of 54 are needed to trigger a vote.

A blow was also landed on the PM from the Sutton Coldfield Conservatives, an association in a safe Tory seat, which reportedly passed a motion calling for Mr Johnson to stand down.

In a rare ray of hope for the Prime Minister, it was reported that an inquiry into alleged lockdown-busting events by senior official Sue Gray was expected to find no evidence of criminality.

However The Times reported that the investigation could censure Mr Johnson for a lack of judgment.

The newspaper said Ms Gray was expected to avoid concluding whether the PM breached the ministerial code, as this would fall outside her remit.

But she is set criticise the culture in Downing Street, it said.

Ms Gray is examining a series of parties and gatherings held in No 10 and Whitehall in 2020 while coronavirus restrictions were in force.

The new allegations that two Downing Street parties took place the week after Philip's death, and on the eve of his funeral, emerged on Thursday evening.

The Telegraph reported that advisers and civil servants gathered after work for two separate events on April 16 2021.

They were to mark the departures of James Slack, Mr Johnson's former director of communications, and one of the PM's personal photographers, the newspaper said.

The Telegraph cited a No 10 spokesperson as saying Mr Johnson was not in Downing Street that day. He is said to have been at Chequers.

It reported accounts from witnesses who said alcohol was drunk and guests danced to music.

The two events are said to have started separately and later merged.

At the time, Government guidance stated: "You must not socialise indoors except with your household or support bubble. You can meet outdoors, including in gardens, in groups of six people or two households."

A Downing Street spokesperson said of Mr Slack's event: "On this individual's last day he gave a farewell speech to thank each team for the work they had done to support him, both those who had to be in the office for work and on a screen for those working from home."

On Wednesday, the Prime Minister apologised for attending a "bring your own booze" party in the Downing Street garden in May 2020, during the first coronavirus lockdown, but insisted he believed it was a work event and could "technically" have been within the rules.

Cabinet ministers defended Mr Johnson after his apology on Wednesday, but the late interventions of Foreign Secretary Liz Truss and Chancellor Rishi Sunak - both tipped as potential successors - did little to instil confidence in his future.

While Mr Johnson endured a difficult session of Prime Minister's Questions on Wednesday, Mr Sunak had notably spent the day away from London on a visit in Devon.

The Prime Minister's official spokesman insisted the Cabinet fully supported Mr Johnson.

But Mr Johnson faced open revolt from one wing of his party, as Scottish Conservative leader Douglas Ross urged him to quit, with almost all Tory MSPs supporting the call.

In Westminster, four other Tory MPs have now publicly said Mr Johnson should go - Mr Bridgen, Sir Roger Gale, former minister Caroline Nokes and chairman of the Public Affairs and Constitutional Affairs Committee William Wragg.

The Metropolitan Police indicated any investigation by them would depend on evidence unearthed in the Gray inquiry.
