Sir Keir Starmer strategically planned to corner Boris Johnson regarding the Partygate scandal. The Labour leader anticipated that when faced with pressure, Mr. Johnson's natural response would be to deceive about the alleged Downing Street parties. Starmer made this calculated move during a session in the Commons, demonstrating his understanding of Johnson's tendencies in difficult situations. This tactic was aimed at holding the Prime Minister accountable for his actions and ensuring transparency in the ongoing investigation into the controversial events at Downing Street.
