A parliamentary system is a form of government where the executive branch derives its legitimacy from and is accountable to the legislature, or parliament. In this system, the head of government, often called the Prime Minister, is typically a member of the parliament and is chosen by fellow members. This creates a close relationship between the legislative and executive branches. In a parliamentary system, the government can be dissolved by a vote of no confidence, allowing for more flexibility in leadership. Elections are usually held to select members of parliament, and the party or coalition with the majority forms the government, influencing policy and decision-making.
