parliament
parliament Legislative assembly that includes elected members and acts as a debating forum for political affairs. Many parliamentary systems are based on the
British Parliament, which emerged in the late 13th century as an extension of the King's Council, and has been housed at Westminster since that time. It is the supreme power in the UK. Parliament comprises the monarch, in whose name members of the government act, and two Houses: the
House of Lords, an upper chamber of peers, bishops, and law lords; and the
House of Commons. There are 659 members of the Commons (known as ‘members of Parliament’ or MPs), elected in single-member constituencies by universal adult suffrage. The prime minister and cabinet members are almost always members of the Commons. There is a maximum of five years between elections. See also
