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.
Tricameralism
The General Synod of the Church of England is sometimes described as tricameral. It is divided into a House of Bishops, the House of Clergy and the House of Laity. As the Church of England is the state church of England, the Parliament of the United Kingdom has given the General Synod the power (subject to veto) to make law relating to the Church.
