The Westminster system or Westminster model is a type of parliamentary government that incorporates a series of procedures for operating a legislature. This concept was first developed in England. Key aspects of the system include an executive branch made up of members of the legislature, and that is responsible to the legislature; the presence of parliamentary opposition parties; and a ceremonial head of state who is different from the head of government. The term comes from the Palace of Westminster, the current seat of the Parliament of the United Kingdom. The Westminster system is often contrasted with the presidential system that originated in the United States, or with the semi-presidential system, based on the government of France. The Westminster system is used, or was once used, in the national and subnational legislatures of most former colonies of the British Empire, upon gaining self-government (with the exception of the United States and Cyprus), beginning with the first of the Canadian provinces in 1848 and the six Australian colonies between 1855 and 1890. It is the form of government bequeathed to New Zealand, and former British Hong Kong. The State of Israel adopted a largely Westminster-inspired system of government upon declaring independence from the British Mandate of Palestine. However, some former colonies have since adopted either the presidential system (Nigeria for example) or a hybrid system (like South Africa) as their form of government. Characteristics The Westminster system of government may include some of the following features: A sovereign or head of state who functions as the nominal or legal and constitutional holder of executive power, and holds numerous reserve powers, but whose daily duties mainly consist of performing ceremonial functions. Examples include King Charles III, the governors-general in the Commonwealth realms, or the presidents of many countries, and state or provincial governors in federal systems. Exceptions to this are Ireland and Israel, whose presidents are de jure and de facto ceremonial, and the latter possesses no reserve powers whatsoever. A head of government (or head of the executive), known as the prime minister (PM), premier, chief minister or first minister. While the head of state appoints the head of government, constitutional convention suggests that a majority of elected members of parliament must support the person appointed. If more than half of elected parliamentarians belong to the same political party, then the parliamentary leader of that party typically is appointed. An exception
