Western countries have the distinction of the parliamentary system, in general terms, can be divided into four modes: 1) the American model: The "separation of powers" is characterized by the implementation of a presidential form of government; 2) French model: "Chief" as the focus on the implementation of semi-presidential system of government; 3) the British model: the "Council", focusing on the implementation of the whole parliamentary system; 4) of the Swiss model: the "Council" as the core, the implementation of the Committee system of government.
The biggest difference between British and American models, and in the "Parliament" and "government" positioning functions. Independent of the Government of the United States Congress, and the British Government to the Cabinet, from Parliament, Cabinet officials and members of Parliament cross-office, a cabinet responsible to Parliament.
Congress and the Government of the United States independent of each other at all levels of government officials responsible directly to the President of the United States, government officials can not act as members of Congress. Britain's close relationship with the Council and the Government, with all countries prospering or declining as one, confidence in the Cabinet if it is not Parliament or the resignation of the cabinet or dissolve parliament. The U.S. Congress and government to maintain independence, President of the United States have no right to dissolve parliament, the Congress has no power of no-confidence motion by the Government.
