A parliamentary system is a form of government where the executive branch derives its legitimacy from the legislature (parliament) and is accountable to it. 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 creates a close relationship between the legislative and executive branches. In a parliamentary system, the government can be dissolved by a vote of no confidence, allowing for more flexibility in leadership. Countries like Canada, United Kingdom, and India use this system, which often leads to coalition governments when no single party gains a majority.
