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 means that the government must maintain the confidence of the parliament to stay in power. In a parliamentary democracy, citizens elect representatives to the parliament, which makes laws and oversees the government. This system encourages collaboration and debate among political parties, allowing for diverse opinions and policies to be considered. Overall, it aims to reflect the will of the people while ensuring a stable government.
