The Prime Minister's implied resignation date has been pushed back by 3 days to 25th September 2026, according to the latest Polymarket betting data. The shift comes as markets assess the likelihood of Keir Starmer remaining in office beyond the previous 22nd September deadline.
The extension of the PM's expected departure date suggests increased confidence among traders that Starmer will continue in his role for the time being, though the ~86% chance of his resignation by the new deadline still points to significant political uncertainty.
