Prime Minister Boris Johnson and Chancellor Rishi Sunak will be fined by the police for breaking lockdown laws.
The PM’s wife, Carrie Johnson, will also be given a fixed penalty notice.
Officials confirmed the three had received notification of the fines from the Met, following an investigation into illegal parties in Downing Street during Covid lockdowns.
Spokespeople for the Johnsons and Mr Sunak said they had not been told which event the fines were linked to.
However, the three were reported to be at the same gathering for the PM’s birthday in June 2020.
Labour leader Sir Keir Starmer and Scotland’s First Minister Nicola Sturgeon said Mr Johnson and Mr Sunak must resign.
And the Covid 19 Bereaved Families for Justice group said there was “simply no way either the prime minister or chancellor can continue”.
Liberal Democrat leader Sir Ed Davey called for Parliament to return from Easter recess so that a no confidence vote could be held.
