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.
Bicameralism
In the German, Indian, and Pakistani systems, the upper houses (the Bundesrat, the Rajya Sabha, and the Senate respectively) are even more closely linked with the federal system, being appointed or elected directly by the governments or legislatures of each German or Indian state, or Pakistani province. This was also the case in the United States before the Seventeenth Amendment was adopted. Because of this coupling to the executive branch, German legal doctrine does not treat the "Bundesrat" as the second chamber of a bicameral system formally. Rather, it sees the "Bundesrat" and the "Bundestag" as independent constitutional bodies. Only the directly elected "Bundestag" is considered the parliament. In the German "Bundesrat", the various "Länder" have between three and six votes; thus, while the less populated states have a lower weight, they still have a stronger voting power than would be the case in a system based "purely" on population, as the most populous "Land" currently has about 27 times the population of the least populous. The Indian Upper House does not have the states represented equally, but on the basis of their population.
