A large £978 bet on Polymarket suggests there is around a 95% chance that Prime Minister Keir Starmer will announce his resignation from Downing Street by July 31, according to the market's implied probability.
The anonymous trader 'Dead-Skylight' closed a position betting that Starmer will depart as PM by the end of this month, in a sign that the political betting market sees his tenure coming to an end sooner rather than later.
