The date by which Keir Starmer is expected to resign as Prime Minister has been pushed back by 2 days, from 14 Aug 2026 to 16 Aug 2026, according to the latest Polymarket betting data.
The shift in the implied resignation date comes as markets assess the latest political developments around the Prime Minister's future. Starmer remains under pressure from some Labour MPs, but continues to insist he will lead the party into the next general election.
