A £1,714 Polymarket bet suggests there is around a 95% chance that Prime Minister Keir Starmer will announce his resignation by June 30, according to the market's implied probability.
The large trade, made by user 'Nautical-Mast-Heyday', closed a position betting on Starmer's exit from Downing Street by the end of this month. The market's pricing implies the resignation is highly likely to be announced before the end of June.
