A £7,711 Polymarket bet has been placed on Prime Minister Keir Starmer leaving Downing Street by December 31, suggesting an ~98% chance of his resignation being announced by that date, according to the market data.
The large trade, made by a user named 'Broken-Pet', closed a position betting on Starmer's exit by the end of the year. The high-stakes wager underscores growing speculation about the PM's political future.
