A £6,126 bet has been placed on the Polymarket platform, indicating a 100% implied probability that Prime Minister Keir Starmer will announce his resignation by July 31. The large trade was made by an account named 'Profitable-Recorder'.
The Polymarket market suggests the resignation is now seen as a near-certainty, with the odds implying around an ~86% chance Starmer will step down as PM by the end of this month.
