List of prime ministers of Charles III
Charles III is head of state of 15 Commonwealth realms and has had 17 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 two new prime ministers; Rishi Sunak as Prime Minister of the United Kingdom on 25 October 2022 and Chris Hipkins as Prime Minister of New Zealand on 25 January 2023. 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, dependancies, or provinces. List of prime ministers
