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.
Devolution in the United Kingdom
There have been proposals for the establishment of a single devolved English Parliament to govern the affairs of England as a whole. This has been supported by groups such as English Commonwealth, the English Democrats and Campaign for an English Parliament, as well as the Scottish National Party and Plaid Cymru who have both expressed support for greater autonomy for all four nations while ultimately striving for a dissolution of the Union. Without its own devolved Parliament, England continues to be governed and legislated for by the UK Government and UK Parliament which gives rise to the West Lothian question. The question concerns the fact that, on devolved matters, Scottish MPs continue to help make laws that apply to England alone, although no English MPs can make laws on those same matters for Scotland. Since the Scottish independence referendum, 2014 there has been a wider debate about the UK adopting a federal system with each of the four home nations having its own, equal devolved legislatures and law-making powers.
