The Parliament of the United Kingdom, commonly known as the UK Parliament or 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 the City of Westminster, one of the boroughs of the British capital, London.
The Parliament Act 1911 is an Act of the Parliament of the United Kingdom.
 It is constitutionally important and partly governs the relationship between the House of Commons and the House of Lords which make up the two Houses of Parliament.
 This Act and the Parliament Act 1949 are technically to be construed as complementary in their effects.
 The two Acts may be cited together as the Parliament Acts 1911 and 1949.
The House of Lords of the United Kingdom, also known as the House of Peers, is the upper house of the Parliament of the United Kingdom.
 Like the House of Commons, it meets in the Palace of Westminster.
 Officially, the full name of the house is: The Right Honourable the Lords Spiritual and Temporal of the United Kingdom of Great Britain and Northern Ireland in Parliament assembled.
The Lords Commissioners are Privy Counsellors appointed by the Monarch of the United Kingdom to exercise, on his or her behalf, certain functions relating to Parliament which would otherwise require the monarch's attendance at the Palace of Westminster.
 These include the opening and prorogation of Parliament, the confirmation of a newly elected Speaker of the House of Commons and the granting of Royal Assent.
 The Lords Commissioners are collectively known as the Royal Commission.
 The Royal Commission includes at least three—and usually five—Lords Commissioners.
 In current practice, the Lords Commissioners usually include the Lord Chancellor, the Archbishop of Canterbury (who is named but usually does not participate), the leaders of the three major parties in the House of Lords, the convenor of the House of Lords Crossbenchers and (since 2007) the Lord Speaker of the House of Lords.
The Parliament of Ireland was the legislature of the Lordship of Ireland, and later the Kingdom of Ireland, from the 13th century until 1800.
 It was modelled on the Parliament of England and from 1537 comprised two chambers: the House of Commons and the House of Lords.
 The Lords were members of the Irish peerage ("lords temporal") and bishops ("lords spiritual"; after the Reformation, Church of Ireland bishops).
 The Commons was directly elected, albeit on a very restricted franchise.
 Parliaments met at various places in Leinster and Munster, but latterly always in Dublin: in Christchurch Cathedral (15th century), Dublin Castle (to 1649), Chichester House (1661–1727), the Blue Coat School (1729–31), and finally a purpose-built Parliament House on College Green.
The British-American Parliamentary Group is a all-party parliamentary group consisting of members of the Parliament of the United Kingdom.
 “The objects of the British-American Parliamentary Group are to promote friendly relations and mutual understanding between Members of both Houses of Parliament of the United Kingdom and Members of both Houses of Congress of the United States of America; to discuss problems common to the United Kingdom and the United States; to exchange courtesies and to provide opportunities for discussion with Senators, members of the House of Representatives, and other distinguished citizens of the United States; and to arrange for the exchange of visits and information between legislators of both countries.”
 Its co-presidents are the Speaker of the House of Commons and the Lord Speaker, among the vice presidents are former Speakers of the House of Commons, one former prime minister, the current deputy prime minister, former leaders of the opposition, and former foreign secretaries.
 The chairman is the prime minister.
 There are currently over 600 members from both the Labour and Conservative parties.
The Parliamentary War Memorial, also known as the Recording Angel Memorial, is a stone sculpture in Westminster Hall, unveiled in 1922, which commemorates the members of both Houses of Parliament of the United Kingdom who died in the First World War.
 It names 22 members of the House of Commons, 20 members of the House of Lords, and 9 senior members of staff, together with another 94 sons of members and officers of the House of Commons, who lost their lives in the war.
 (Sons of peers and of officers of the House of Lords are commemorated on the wooden panels of the House of Lords War Memorial in the Royal Gallery.)
 Above the memorial is a large stained glass window which commemorates members and staff of both Houses who died in the Second World War.
The Parliamentary Office of Science and Technology, (POST) is the Parliament of the United Kingdom's in-house source of independent, balanced and accessible analysis of public policy issues related to science and technology.
 POST (rather distinctively) serves BOTH Houses of Parliament (the House of Commons and equally the House of Lords) as a joint establishment, through output that is apolitical and of widely acclaimed value to Parliamentarians of all parties.
 Thorough quality-control, which POST has pioneered, ensures that MPs and Peers can have confidence in its analyses should they wish to cite them in debate.
 These principles are reflected in the structure of POST’s Board with members from the Commons and Lords together with distinguished scientists and engineers from the wider world.
 The choice of the word "of" rather than "for" in the office's title was a formal recognition of a fundamental consideration.
 POST was not, in any way, to be a body promoting special interests of the science and technology community, particularly funding levels.
 Rather it was to provide analysis and interpretation of issues, current and prospective, with a significant scientific or technological dimension.
 POST was not expected to make recommendations for any specific policy but to set out the "choices" in terms of policy options that were available to address any particular issue.
