In a parliamentary system, the head of government is usually the prime minister.
The prime minister is the leader of the political party or coalition that has the majority in the parliament. They are responsible for running the day-to-day affairs of the government and making important decisions.
Unlike a president, who is elected separately from the parliament, the prime minister is chosen by the members of the parliament. This means that the prime minister is accountable to the parliament and can be removed from office if they lose the support of the majority of the members.
The role of the prime minister is crucial in a parliamentary system as they represent the executive branch of government and serve as the main link between the parliament and the monarch or president. They are responsible for proposing and implementing laws, managing the government's policies, and representing the country in international affairs.
