The difference between American political system and British political system
The American political system
The United States is a federal constitutional republic, in whtates (the head of state and head of government), Congress, and judiciary share powers reserved to the national government, and the federal government shares sovereignty with the state governments.

The executive、legislature and judiciary
As a parliamentary democracy,the british government is characterized by a division of powers among the legislature,the executive and the judiciary.However,the division among these three branches is not so absolute as that in the united states,because the prime Minister,the head of the executive branch,is also the leader of the majority party in parliament.Futhermore,he advises the monarch on the candidates of judges of the supreme court.
