A large £7.6k Polymarket bet has signalled a 100% chance that Prime Minister Keir Starmer will resign from office by June 22, according to the market's implied probability.
The trade, made by an anonymous user 'Organic-Test', closed a position betting that Starmer will leave Downing Street by the end of next month. The market now indicates a near-certainty that the Prime Minister's resignation will be announced within the next two months.
