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
Many parliaments are part of a parliamentary system of government, in which the executive is constitutionally answerable to the parliament. Some restrict the use of the word "parliament" to parliamentary systems, while others use the word for any elected legislative body. Parliaments usually consist of "chambers" or "houses", and are usually either bicameral or unicameral although more complex models exist, or have existed ("see Tricameralism).
