List of prime ministers of Elizabeth II

Within the Westminster system in each realm, the Queen's government was headed by a prime minister.

Appointment and dismissal of prime ministers were common reserve powers that could be exercised by Elizabeth or her governors-general.

Several of her prime ministers from various realms were appointed for life to the Privy Council of the United Kingdom.

Jawara became President of the Gambia on the same day as the post of prime minister was abolished.

Nkrumah became President of Ghana on the same day as the post of prime minister was abolished.
