Prime Minister Keir Starmer's expected resignation date has been pushed back by 1 day to 1 Oct 2026, according to the latest Polymarket data. The new timeline indicates the PM is now ~86% likely to still be in office on that date.
The shift comes as Starmer faces continued pressure from Labour rebels demanding he step down. However, the Prime Minister has vowed to remain in post until his party can elect a new leader to replace him.
