Boris Johnson is to face MPs later at Prime Minister’s Questions amid demands for him to say whether he attended a drinks event in the Downing Street garden during lockdown.
It will be the PM’s first public appearance since it emerged 100 staff were invited to the May 2020 gathering.
Mr Johnson has so far declined to say whether he attended it.
However, a number of Conservative MPs have said this position is unsustainable.
On Monday, ITV published a leaked email from Mr Johnson’s principal private secretary, Martin Reynolds, inviting staff to “socially distanced drinks in the No 10 garden” on 20 May 2020 – when lockdown rules in England banned large outdoor gatherings.
Witnesses have said the prime minister and his wife Carrie were among about 30 people who attended the drinks.
Liberal Democrat leader Sir Ed Davey said if the prime minister had a “shred of decency left”, he should resign today.
He added Mr Johnson was “incapable of leading the country through this public health crisis”, accusing him of being a “threat to the health of the nation” as the public would not listen to anything he had to say.
