The United States Congressional system and The British Parliamentary System are related in the sense that the former can trace its origins from the latter. They are very much the same in some ways, yet quite different in others.
The British Parliamentary System is commonly referred to as the “mother of all Parliaments”. It is the supreme parliamentary body in the United Kingdom and of its overseas territories. The system has three individual components which are separate from each other. These are: The Crown (Queen), The Upper House which is composed of the House of Lords who are appointed by the Queen, in consultation with the Prime minister, and the Lower House or The House of Commons whose members are directly elected in their constituencies (Pertersen, 2005).
In contrast, the United States Congress, which is the legislative bicameral arm of the Federal government of the United States, is composed of two houses: The Senate and the House of Representatives. The members of these houses are directly elected by citizens of the States for the Senate (each state by two senators) and Districts residents for House of Representatives (Remini, 2007).
