The date by which Prime Minister Keir Starmer is expected to announce his resignation has been brought forward by 3 days, from 9 October 2026 to 6 October 2026 according to the latest Polymarket data.
This shift in the implied resignation date suggests growing market expectations that Starmer's departure could come sooner than previously anticipated. The ~86% probability of Starmer resigning by the new date of 6 October 2026 underscores the increasing uncertainty around his political future.
