King Charles III with former British prime minister Rishi Sunak in 2023
Charles III is head of state of 15 Commonwealth realms and has had 21 prime ministers throughout his reign. Within the Westminster system in each realm, the King's government is headed by a prime minister . Appointment and dismissal of prime ministers are common reserve powers that can be exercised by the King or his governors-general . To date, Charles has appointed six new prime ministers, the first being Rishi Sunak as Prime Minister of the United Kingdom on 25 October 2022 and the most recent being Sir Keir Starmer to the same office on 5 July 2024.
This list does not cover Commonwealth nations that are not Commonwealth realms, as Charles is not head of state in these nations. Nor does it cover holders of offices of prime minister in sub-national entities such as states, dependencies, or provinces.
