Politics of the United Kingdom
The UK Parliament is the supreme legislative body in the United Kingdom (i.e., there is parliamentary sovereignty), and Government is drawn from and answerable to it. Parliament is bicameral, consisting of the House of Commons and the House of Lords. There is also a devolved Scottish Parliament and devolved Assemblies in Wales and Northern Ireland, with varying degrees of legislative authority.
Parliament of the United Kingdom
The House of Commons is an elected chamber with elections to 650 single member constituencies held at least every five years under the first-past-the-post system. The two Houses meet in separate chambers in the Palace of Westminster (commonly known as the Houses of Parliament) in London. By constitutional convention, all government ministers, including the Prime Minister, are members of the House of Commons or, less commonly, the House of Lords and are thereby accountable to the respective branches of the legislature. Most cabinet ministers are from the Commons, whilst junior ministers can be from either House. However, the Leader of the House of Lords must be a peer.
