Current House of Commons

The House of Commons is the lower house of the Parliament of the United Kingdom. Like the upper house, the House of Lords, it meets in the Palace of Westminster. Officially, the full name of the house is the Honourable the Commons of the United Kingdom of Great Britain and Northern Ireland in Parliament assembled. Offices however extend to Portcullis House due to shortage of space.

The Commons is an elected body consisting of 650 members known as Members of Parliament (MPs). Members are elected to represent constituencies by first-past-the-post and hold their seats until Parliament is dissolved.

The House of Commons of England evolved in the 13th and 14th centuries. It eventually became the House of Commons of Great Britain after the political union with Scotland in 1707, and assumed the title of "House of Commons of Great Britain and Ireland" after the political union with Ireland at the start of the 19th century. The "United Kingdom" referred to was the United Kingdom of Great Britain and Ireland from 1800, and became the United Kingdom of Great Britain and Northern Ireland after the independence of the Irish Free State in 1922. Accordingly, the House of Commons assumed its current title.
