An alternative minimalist approach to change provides for removing the sovereign and retaining the governor-general. The most notable model of this type is the McGarvie Model, while Copernican models replace the monarch with a directly-elected figurehead. These Copernican models allow for regular and periodic elections for the office of head of state while limiting the reserve powers to the appointed governor-general only. A popularly elected head of state would have the same powers as the monarch, but he or she could not dismiss the prime minister. If this were to happen, it would be a first, as all other former Commonwealth realms have created presidencies upon becoming republics.
