In a surprise development, the date by which Prime Minister Keir Starmer is expected to announce his resignation has been moved up by 2 days, from 13 September 2026 to 12 September 2026.
The shift in the implied resignation date, based on Polymarket betting data, comes as the PM faces growing pressure from within his own party. Starmer has not yet confirmed plans to step down, but the updated date suggests his exit could come sooner than previously anticipated.
