Description
A parliamentary system, or parliamentary democracy, is a form of government where the head of government derives their democratic legitimacy from their ability to command the support ("confidence") of a majority of the legislature, to which they are held accountable. This head of government is usually, but not always, distinct from a ceremonial head of state. This is in contrast to a presidential system, which features a president who is not fully accountable to the legislature, and cannot be replaced by a simple majority vote.
