Chambers of parliament

Many parliaments or other legislatures consist of deliberative assembly in two legislative chambers (or houses): an elected lower house, and an upper house or Senate which may be appointed or elected by a different mechanism from the lower house. This style of two houses is called bicameral. Legislatures with only one house are known as unicameral.

The lower house is almost always the originator of legislation, and the upper house is the body that offers the "second look" and decides whether to veto or approve the bills. In the United Kingdom legislation can be originated in either house, but the lower house can ultimately prevail if the two houses repeatedly disagree. In most countries the lower house, regarded as more particularly the representatives of the people, has sole or predominant control over matters to do with finance and taxation.

A parliament's lower house is usually composed of at least 100 members, in countries with populations of over 3 million. The number of seats rarely exceeds 400, even in very large countries. Among the countries with large lower houses are France, where the National Assembly has 577 members, and Japan, where the House of Representatives has 475 members. The upper house of a parliament customarily has anywhere from 20 to 200 seats, but almost always significantly fewer than the lower house. In the United Kingdom however, the lower house (the House of Commons) has 650 members, but the upper house (the House of Lords) currently has slightly more members than the lower house, and at one time (before the exclusion of most of the hereditary peers) had considerably more.

House of Commons

The House of Commons is the name of the elected lower house of the bicameral parliaments of the United Kingdom and Canada and historically was the name of the lower houses of Ireland, Northern Ireland, and North Carolina. Roughly equivalent bodies in other countries which were once British colonies or federations thereof include the United States House of Representatives, the Australian House of Representatives, the New Zealand House of Representatives, and India's Lok Sabha.

In the UK and Canada, the Commons holds much more legislative power than the respective upper house of parliament. The leader of the majority party in the House of Commons usually becomes the prime minister. Since 2010 the House of Commons of the United Kingdom has had 650 elected members, and since 2015 the House of Commons of Canada has had 338 members. The Commons' functions are to consider through debate new laws and changes to existing ones, authorise taxes, and provide scrutiny of the policy and expenditure of the Government. It has the power to give a Government a vote of no confidence.

Parliament

In modern politics and history, a parliament is a legislative, elected body of government. Generally a modern parliament has three functions: representing the electorate, making laws, and overseeing the government (i.e., hearings, inquiries).

Although some restrict the use of the word parliament to parliamentary systems, it is also commonly used to describe the legislature in presidential systems (i.e. the French parliament), even where it is not in the official name.

Historically, parliaments included various kinds of deliberative, consultative, and judicial assemblies (i.e. the mediaeval parlements).

Etymology

The term is derived from Anglo-Norman parlement, from the verb parler 'talk'. The meaning evolved over time: originally any discussion, conversation, or negotiation (attested around 1100), through various kinds of deliberative or judicial groups, often summoned by the monarch. By 1400, it had come to mean in Britain specifically the British supreme legislature.

Origins

Various parliaments are claimed to be the oldest in the world, under varying definitions:

Parliament of the United Kingdom

The Parliament of the United Kingdom of Great Britain and Northern Ireland, commonly known as the UK Parliament or the British Parliament, is the supreme legislative body in the United Kingdom, British Crown dependencies and British overseas territories. It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and its territories. Its head is the Sovereign of the United Kingdom (currently Queen Elizabeth II) and its seat is the Palace of Westminster in Westminster, London.

The parliament is bicameral, consisting of an upper house (the House of Lords) and a lower house (the House of Commons). The Sovereign forms the third component of the legislature (the Queen-in-Parliament). The House of Lords includes two different types of members: the Lords Spiritual, consisting of the most senior bishops of the Church of England, and the Lords Temporal, consisting of members of the peerage and life peers who are appointed by the Sovereign on the advice of the Prime Minister. Prior to the opening of the Supreme Court in October 2009, the House of Lords also performed a judicial role through the Law Lords.

House of Lords

The House of Lords is the upper house of the Parliament of the United Kingdom. Like the House of Commons, it meets in the Palace of Westminster.

Unlike the elected House of Commons, most members of the House of Lords are appointed. The membership of the House of Lords is made up of Lords Spiritual and Lords Temporal. The Lords Spiritual are 26 bishops in the established Church of England. Of the Lords Temporal, the majority are life peers who are appointed by the monarch on the advice of the Prime Minister, or on the advice of the House of Lords Appointments Commission. However, they also include some hereditary peers including four dukes. Membership was once an entitlement of all hereditary peers, other than those in the peerage of Ireland, but under the House of Lords Act 1999, the right to membership was restricted to 92 hereditary peers. Very few of these are female since most hereditary peerages can only be inherited by men.

While the House of Commons has a defined 650-seat membership, the number of members in the House of Lords is not fixed. There are currently 816 sitting Lords. The House of Lords is the only upper house of any bicameral parliament to be larger than its respective lower house.
