The United Kingdom UK and the United States US stand out
1) While the president is the head of state as well as head of government in the United States, that office does not have the same power as the British Prime Minister. Further, while Congress makes the laws in the United States, Parliament is essentially the entire government.
2) The USA practices the federal constitutional republic form of government while the UK uses constitutional monarchy and a parliamentary system.
3) USA has 50 states whereas the UK is a single state kingdom comprised of different countries; the United Kingdom, made up of England, Scotland, Wales and Northern Ireland, is an island nation in northwestern Europe.
4) The major difference between these two systems is that in a Presidential system, the executive leader, the President, is directly voted upon by the people or via a body elected specifically for the purpose of electing the president, and no other purpose, and the executive leader of the Parliamentary system, the Prime Minister.
