One major difference between the governmentsof the United States and Great Britain lies in the separation of powers in the U.S. andthe parliament system in the UK, where parliament holds the majority of the power and the prime minister is subject to their wishes.In the United States, powers can be shared by the House of Representatives and the Senate, but the president has the power to veto any legislation passed by congress.
In England, the prime minister must attend a weekly mandatory meeting in front of the House of Commons and answer questions asked by parliament. The prime ministeris directly responsible to the governing body because the prime minister is directly appointed fromamong their ranks. If the prime minister loses support of the majority of parliament on a specific vote, he must resign and anew election must beheld immediately.
In the United States, there is a separation of powers between Congress and the president. The House of Representatives and the Senate are responsible for creating and passing laws; bills must be supported by the majority in both legislators to become laws. The president holds veto power and can stop a bill from becoming law after it clears congress.
