The probability of Prime Minister Keir Starmer resigning by June 23 has surged by 8 percentage points to around 92% on Polymarket, a major shift in the closely watched political betting market.
The spike in Starmer's resignation odds comes amid growing pressure on the PM from within his own party, with the number of Labour MPs publicly demanding he step down now standing at a significant level.
Starmer has faced a turbulent period in recent weeks, with his leadership coming under intense scrutiny as the party grapples with a range of policy and political challenges.
