The House of Lords (commonly referred to as "the Lords", officially referred to as the "Lords Spiritual and Temporal" in Acts of Parliament, and also known as House of Peers for ceremonial purposes) is the upper house of the Parliament of the United Kingdom, the United Kingdom's national legislature. Parliament comprises the Sovereign, the House of Commons (which is the lower house of Parliament and referred to as "the Commons"), and the Lords. The House of Lords, like the House of Commons, assembles in the Palace of Westminster.
The House of Lords as an upper chamber has the primary purpose of scrutinising Legislation proposed by the Lower House through the form of debate and through proposing amendments to legislation. Governments in recent years have used the Upper House as a variant of the Select Committee process to finalise legislation before presentation for Royal Assent. Bills are able to be introduced into either House for debate and reading but due to the need for the Lower House's consent Bills are almost always introduced in the House of Commons. Peers of the House of Lords may also be in Cabinet but in recent years it is generally rare for high profile positions to be granted to members due to the appointment and Hereditary positions of those within the House. The Speech from the Throne is delivered from the House of Lords, a tradition still emulated in other Commonwealth Realms, as a reminder of the constitutional position of the Monarch. The House also has a minor Church of England role in that through the Lords Spiritual Church Measures must be tabled within the House.
The formal title of the House of Lords is The Right Honourable the Lords Spiritual and Temporal of the United Kingdom of Great Britain and Northern Ireland in Parliament assembled.
