What is Parliamentary System?

Parliamentary System of Government

Quick Answer

A parliamentary system is a type of government where the executive branch derives its legitimacy from and is directly accountable to the legislature or parliament. In this system, the head of government is usually called the Prime Minister and is elected by the parliament, rather than by a separate electoral process.

Overview

In a parliamentary system, the government is formed by the political party or coalition that has the most seats in parliament. The Prime Minister, who leads the government, is typically a member of the parliament and is chosen by fellow members. This close relationship between the legislative and executive branches allows for easier passing of laws and policies, as the Prime Minister usually has the support of the majority of parliament members. One key feature of parliamentary systems is the ability for the parliament to remove the Prime Minister through a vote of no confidence. This means that if the Prime Minister loses the support of the majority, they can be replaced without waiting for a general election. This system encourages leaders to remain responsive to the needs and opinions of the parliament and, by extension, the public. Countries like the United Kingdom and Canada exemplify parliamentary systems, where the Prime Minister leads the government while being accountable to parliament. This system is important in the political landscape because it promotes cooperation and can lead to more stable governance, as the executive branch is supported by the legislative branch.
