A key feature of a parliamentary democracy is the fusion of executive and legislative powers. In this system, the executive branch derives its legitimacy from the legislature and is accountable to it. The head of government, usually a prime minister, is elected by the majority party or coalition in the parliament. This interdependence fosters collaboration on policy decisions and promotes stability, but it can also lead to challenges in governance if there is a lack of consensus. Additionally, parliamentary systems often allow for more direct public representation through party platforms.
