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.
Statutory authority
A statutory authority is a body set up by law which is authorised to enact legislation on behalf of the relevant country or state. They are typically found in countries which are governed by a British style of parliamentary democracy such as the UK and British Commonwealth countries like Canada, Australia, New Zealand and India. They are also found in Israel and elsewhere. In Britain, many such bodies are termed QUANGOs because of their semi-autonomous nature.
