- Westminster system - Glossary Term
A system of parliamentary government, also known as responsible government, which evolved in England and was adopted in its colonies, including Australia. It is based on the principle that the executive government is responsible to the people through the parliament. The executive government is formed by those who command the support of the lower House of Parliament. Ministers, including the Prime Minister, are members of a House of Parliament and are accountable to it. There is a separate, largely ceremonial, head of state, an independent public service and an independent judiciary that applies the rule oflaw.
