The implied resignation date for Prime Minister Keir Starmer has been pushed back by 3 days to 25 Sept 2026, according to the Polymarket prediction market. The shift from the previous 22 Sept date indicates the PM is now less likely to step down by the earlier deadline.
Polymarket's ~86% probability of Starmer remaining PM on 25 Sept suggests the Labour leader has stabilised his position, at least in the short term. However, the market still implies a high chance of his resignation in the coming months.
