The Prime Minister's expected resignation date has been pushed back by 1 day to 22 July 2026, according to the latest Polymarket data. The shift comes as markets adjust their expectations around Keir Starmer's future as Labour leader.
The new date of 22 July 2026 represents an ~86% chance that Starmer will still be PM on that date, up from the previous ~86% chance he would depart by 21 July 2026.
