In a parliamentary system, the head of state serves primarily as a ceremonial figure, distinct from the head of government, who is responsible for day-to-day administration. The head of state, such as a monarch or president, may perform functions like opening sessions of parliament or representing the nation in diplomatic matters but typically has limited political power. This separation ensures that the elected Prime Minister and cabinet can govern effectively, fostering accountability and democratic processes. However, the head of state's role can vary by country, with some holding more symbolic or influential positions depending on the system's specific configuration.
