A large £4,300 bet has been placed on Polymarket that Prime Minister Keir Starmer will leave Downing Street by December 31. The trade implies around a ~77% chance that Starmer's resignation will be announced by the end of the year.
The anonymous trader, known as 'Pristine-Business', opened the position on the December 31 market, suggesting they believe there is a high probability Starmer will no longer be PM within the next few months.
