The Prime Minister's expected resignation date has been brought forward by 6 days, from 11th September 2026 to 6th September 2026, according to Polymarket data. This suggests the PM's position may be weakening, with an ~86% chance he will have stepped down by the new date.
The shift in Starmer's expected departure comes amid ongoing speculation about his leadership. The Prime Minister has faced growing pressure from Labour backbenchers, with a number of MPs publicly calling for him to resign in recent weeks.
