A parliamentary democracy is a system of government where the executive branch derives its legitimacy from and is accountable to the legislature, or parliament. In this setup, the head of government, often called the Prime Minister, is typically a member of the parliament and is chosen by fellow members. This structure allows for a close relationship between the legislative and executive branches. In a parliamentary democracy, elections are held to select representatives who make laws and govern on behalf of the people. The government can be dissolved and new elections called if it loses the confidence of the parliament, ensuring that the leadership remains responsive to the electorate's needs.
