Westminster system

The Westminster system, or Westminster model, is a type of parliamentary government modelled on that of the Parliament of the United Kingdom. Key aspects of the system include an executive branch made up of members of the legislature which is responsible to the legislature; the presence of parliamentary opposition parties; and a ceremonial head of state who is separate from the head of government. The term derives from the Palace of Westminster, the seat of the British parliament.
