The odds of Prime Minister Keir Starmer resigning by June 22 have drifted to around 57% on Polymarket, down 5 percentage points from 62% previously.
This shift in the market's implied probability suggests growing uncertainty over whether Starmer will step down as Labour leader by the end of next month, as some have speculated.
The Polymarket betting market is widely watched as a real-time indicator of political sentiment and expectations around key events.
