A Commonwealth realm is a sovereign state in the Commonwealth of Nations that has the same constitutional monarch and head of state as the other realms. The current monarch is King Charles III. Except for the United Kingdom, in each of the realms the monarch is represented by a governor-general. The phrase Commonwealth realm is an informal description not used in any law.
