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.
Politics of Bahrain
The opposition led by Islamic parties boycotted the 2002 election in protest at the bicameral nature of the parliament, because the appointed upper chamber, the Shura Council, has the power to veto legislation. Shura members have responded by pointing out that an appointed upper chamber is a feature of long established democracies such as the United Kingdom (where the upper chamber has power to delay, but no power to veto legislation) 
and Canada.
