BBC: Boris Johnson will be fined by the police for attending a birthday party thrown for him during a Covid lockdown.
No 10 confirmed the PM would receive the fixed penalty notice (FPN) for going to the hour-long gathering in the Cabinet Room on 19 June 2020.
It comes as part of a Met investigation into illegal parties in Downing Street.
Mr Johnson’s fine makes him the UK’s first serving prime minister to be sanctioned for breaking the law.
Labour leader Sir Keir Starmer, Scotland’s First Minister and SNP leader Nicola Sturgeon, and Wales’ Labour First Minister Mark Drakeford are among those calling for both the PM and the chancellor to resign.
And all the main opposition parties in Westminster have demanded Parliament be recalled from its Easter break.
But Culture Secretary Nadine Dorries defended the PM for attending the event, tweeting: “It was a brief gathering in the Cabinet Room, less than 10 minutes during a busy working day.”
