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.
Asymmetric federalism
In the United Kingdom, England has no self-government and is ruled directly by the British Parliament, but Scotland, Northern Ireland and Wales have varying degrees of autonomy. However, many people believe that asymmetrical devolution of powers (most notably to the Scottish Parliament and Welsh Assembly) is unfair, which causes the ongoing West Lothian question. The United Kingdom is a unitary state, not a federal one, according to its constitution, and the British Parliament still remains sovereign.
