A £1,009 Polymarket bet has been placed suggesting around a 30% chance that Prime Minister Keir Starmer will still be in office on June 30, according to the market's implied probability.
The trade, made by user 'Hoarse-Wastebasket', closed a position backing Starmer to remain PM past the June 30 date, indicating the market sees a ~70% chance of his exit by that point.
