Keir Starmer's odds of remaining as Prime Minister past July 31 have risen by 9 percentage points to around 49%, according to the latest Polymarket betting data. The increase suggests a growing belief that the Labour leader will still be in office after the end of this month.
The shift in market sentiment comes as Starmer continues to face internal pressure, with the number of Labour MPs publicly calling for his resignation now standing at around 86 of the party's 199 MPs.
Despite the rising odds, the Prime Minister has so far resisted calls to step down and has vowed to lead Labour into the next general election.
