Boris Johnson has been told to quit after a Metropolitan Police investigation concluded covid laws were broken in Number 10 during the height of lockdown.
Labour leader Sir Keir Starmer said the Prime Minister had "knowingly misled" MPs over the Christmas parties held in Downing Street, after 20 fines were issued for rule breaches.
The decision to issue fixed penalty notices means the police believe the law was broken – with more fines expected to follow as officers continue to sift through evidence.
