Prime Minister Keir Starmer's expected resignation date has been pushed back by 1 day to 13 August 2026, according to the latest Polymarket data. The date shift comes as markets assess the likelihood of Starmer remaining in office past the previous 12 August 2026 prediction.
The change in expected resignation timing reflects updated assessments of Starmer's political future, though the ~86% implied probability of his departure by the new date remains unchanged.
