In a parliamentary system, the roles of the head of state and head of government are typically separated. The head of state (ceremonial role) and head of government (executive role) are held by different individuals, such as the monarch and the Prime Minister, respectively, in the case of the United Kingdom. The head of state (the monarch, in this case) primarily performs ceremonial functions, while the head of government (the Prime Minister) holds executive authority and is responsible for running the government.
