The House of Representatives
435 members are elected in a first-past-the-post system to the House of Representatives, every two years to represent a particular congressional area or constituency, which is calculated by population rather than geographical area, unlike the UK. If a single candidate does not secure fifty percent of the vote, run-offs are then held until a winner emerges.
There are also five non-voting members or delegates, who observe proceedings and can stand on specific committees from Guam, The Virgin Islands, American Samoa, the North Mariana Islands and the District of Columbia.
Like the House of Commons, Congress is presided over by The Speaker of the House, chosen by the majority party but has more power than his British counterpart in forming the agenda of parliamentary debate.The House of Representatives meet in the south wing of the Capitol in Washington DC.
