In a parliamentary system, by contrast, the legislature holds supreme power. The prime minister is chosen by members of the legislature (Parliament) from among their own number and in practice is the leader of the majority party in the legislature.
There are 435 Representatives in the House of Representatives. The number of members in the House of Representatives is a different story and is based on population.
The House currently consists of 435 voting members, each of whom represents a congressional district. The number of representatives each state has in the House is based on each state's population as determined in the most recent United States Census. All 435 representatives serve a two-year term. Each state receives a minimum of one representative in the House.
