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 system, the head of government, often called the Prime Minister, is typically a member of the parliament and is chosen by fellow members. This structure promotes collaboration 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. Political parties play a significant role, and the party with the majority usually forms the government. This system allows for more flexible governance and can lead to quicker decision-making compared to other forms of democracy.
