Boris Johnson will face a parliamentary misconduct investigation, after MPs backed a crunch House of Commons motion over his breaches of coronavirus laws.
The Labour motion, which was unopposed by the Government, means the Partygate scandal will be referred to the privileges committee - which can determine whether the Prime Minister's repeated denials of there being any parties in Number 10 during the height of lockdown amounted to a "contempt of the House".
By convention, if a Government minister is found to have misled Parliament they are expected to resign or are usually sacked.
