The Commonwealth Realms are a group of 15 sovereign states that share King Charles III as their monarch and are members of the Commonwealth of Nations. These countries are spread across the globe, with the United Kingdom being the largest and most influential member. Other members include Australia, Canada, New Zealand, and several Caribbean and Pacific island nations. Although the monarch is the symbolic head of state, each Commonwealth realm operates as a separate and independent nation with its own government and constitution. These countries share a rich history and cultural ties through their shared heritage and membership in the Commonwealth, which serves as a platform for cooperation and collaboration in areas such as trade, education, and human rights.

States must complete whatever process they choose for removing the monarch, it cannot simply be that they have announced an intention to.
