A Commonwealth realm is a sovereign state that has Charles III as its monarch and ceremonial head of state. All the realms are equal with and independent of the others, though one person, resident in the United Kingdom, acts as monarch of each. The phrase Commonwealth realm is an informal description not used in any law.
