# How many UK Prime Ministers by end of 2027?

Live · $175,858 traded · listed on Polymarket

## About

This market will resolve to the number of unique individuals who officially hold the office of Prime Minister of the United Kingdom at any point between market creation and December 31, 2027, 11:59 PM ET.

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.
