Andy Burnham’s July 2026 takeover as Prime Minister after Keir Starmer’s resignation has reset the count at two leaders, and traders see strong odds that this remains the total through the end of 2027. Labour’s large parliamentary majority, inherited from the 2024 election and not due for renewal until 2029, reduces the chance of an early general election that could force another change. Burnham has already signaled continuity by ruling out a snap vote and consolidating support within the party. A third Prime Minister would require either a successful internal challenge or resignation driven by economic headwinds, slipping poll numbers, or policy setbacks—scenarios priced at just 14.5 percent given the fresh leadership honeymoon and lack of immediate rivals. Multiple additional turnovers look even more remote at 1.2 percent, as the structural barriers to rapid successive leadership crises remain high absent a major external shock.

This market will resolve based on the number of unique individuals to hold the position. For example, if an individual is appointed twice within the specified timeframe, they will only count once for resolution.
To count for resolution, an individual must have been officially appointed by the United Kingdom Monarch. An individual’s time of appointment will have no bearing on this market so long as the individual officially serves as Prime Minister within the specified timeframe. Any interim or caretaker Prime Minister will not count toward the resolution of this market
For clarity, Keir Starmer will count as one Prime Minister for the purposes of this market.
The primary resolution source for this market will be official information from the Government of the United Kingdom; however, a consensus of credible reporting may also be used.
