A £1,100 Polymarket bet has been placed on Prime Minister Keir Starmer remaining in office past August 31, according to the betting platform's data. The trade implies just a ~3% chance that Starmer will have stepped down by that date.
The large position suggests some market participants believe Starmer is likely to still be PM on August 31, despite growing calls from Labour MPs for him to resign. The Polymarket market on Starmer's future is thinly traded, with limited liquidity.
