A large £1,127 Polymarket trade has been placed on the outcome that Prime Minister Keir Starmer will leave Downing Street by June 30. The market currently implies around a ~90% chance the resignation will be announced by that date.
The 'Yes' token in the market, which pays out if Starmer resigns by June 30, has seen significant buying activity. Traders appear to be betting that the Prime Minister's position has become untenable and that he may step down in the coming weeks.
