The false statement when comparing the political systems of the United States and Great Britain is:
Both countries contain three branches of government with equal amounts of power.
In the United States, the three branches of government (executive, legislative, and judicial) are designed to have separate powers and checks and balances to ensure that no branch becomes too powerful. However, in Great Britain, the system is a parliamentary system where the executive branch (the Prime Minister and the Cabinet) is drawn from the legislative branch (Parliament), which means that the branches do not have an equal distribution of power as they do in the U.S. system.
