House of Commons
The House of Commons is the lower house of the bicameral parliament both in the United Kingdom and Canada, and in the UK consists of 646 elected members. Historically, the term has also been used in Ireland, South Korea and the state of North Carolina in the USA.
Within the House of Commons, the party leader of the majority party usually becomes the Prime Minister. Some purposes of the House of Commons are to debate new or alter existing laws and monitor the expenditure of the Government. The House of Commons also has the power to give a Government a 'vote of no confidence' which is put forward by the opposition in hope of defeating a government. The British House of Commons was originally created to represent commoners such as craft guilds and tenants, while the 'elite' estates were represented by the House of Lords and appointed on the basis of hereditary titles and such like. The term "commons" in House of Commons, is derived from the Anglo-Norman word communes, which referred to the respective geographic and collective "communities" of their representatives and not in fact their commonality.
