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.
Sweden
In 1866 Sweden became a constitutional monarchy with a bicameral parliament, with the First Chamber indirectly elected by local governments, and the Second Chamber directly elected in national elections every four years. In 1971 the parliament became unicameral. Legislative power was (symbolically) shared between the King and the Riksdag until 1975. Swedish taxation is controlled by the Riksdag.
