(FILES) In this file photo taken on May 24, 2022 Britain's then prime minister Boris Johnson adjusts his tie at the start of a cabinet meeting at 10 Downing Street in London. Johnson announced his resignation as an MP on June 9, 2023, accusing a parliamentary probe into the "Partygate" scandal of driving him out. Johnson, 58, said he was stepping down with immediate effect "triggering an immediate by-election" in his marginal seat, which heaps political pressure on his successor Rishi Sunak.
