Prime Minister Keir Starmer is facing an earlier resignation deadline, with Polymarket odds shifting to suggest he may step down as Labour leader by 12 September 2026 - 5 days earlier than the previous 17 September 2026 expectation.
The change in Polymarket's implied resignation date comes as the platform adjusts its odds, reflecting growing market sentiment that Starmer could be forced out sooner than previously anticipated. The PM has faced increasing pressure from within his own party in recent weeks.
