Charles III reigns as king of 15 independent countries known as the Commonwealth realms. He resides primarily in the oldest and most populous realm, the United Kingdom, and is represented in the other countries by the following viceregal representatives. The monarch is also represented in each of the Canadian provinces, Australian states, British overseas territories, Crown dependencies, and the states in free association with New Zealand.
In the United Kingdom, the sovereign appoints counsellors of state to act on the monarch's behalf when he or she is not present in the country or unable for other reasons to perform royal constitutional functions.
Crown dependencies
The Crown dependencies are possessions of the Crown of the United Kingdom, not of the government of the United Kingdom, and the British monarch is head of state, represented by lieutenant governors.
