The Chamber of Deputies () is the lower house of the bicameral Italian Parliament (the other being the Senate of the Republic). The two houses together form a perfect bicameral system, meaning they perform identical functions, but do so separately. The Chamber of Deputies has 400 seats, of which 392 will be elected from Italian constituencies, and 8 from Italian citizens living abroad. Deputies are styled The Honourable (Italian: Onorevole) and meet at Palazzo Montecitorio. Location The seat of the Chamber of Deputies is the Palazzo Montecitorio, where it has met since 1871, shortly after the capital of the Kingdom of Italy was moved to Rome at the successful conclusion of the Italian unification Risorgimento movement. Previously, the seat of the Chamber of Deputies of the Kingdom of Italy had been briefly at the Palazzo Carignano in Turin (1861–1865) and the Palazzo Vecchio in Florence (1865–1871). Under the Fascist regime of Benito Mussolini, the Chamber of Deputies was abolished and replaced by the figurehead Chamber of Fasces and Corporations from 1939 to 1943 (during World War II). Normal operation The Chamber is composed of all members meeting in session at the Montecitorio. The assembly also has the right to attend meetings of the Government and its ministers. If required, the Government is obligated to attend the session. Conversely, the Government has the right to be heard every time it requires. The term of office of the House (as well as the Senate) is five years, but can be extended in two cases: The "prorogatio", as provided by art. 61.2 of the Constitution, states that deputies whose terms have expired shall continue to exercise their functions until the first meeting of the new Chamber. An extension of the term, provided for by art. 60.2, can be enacted only in case of war. Electoral system The electoral system is a mixed-member majoritarian with 37% of seats allocated using first-past-the-post voting (FPTP) and 63% using proportional representation, allocated with the largest remainder method, with one round of voting. The 400 deputies are elected in: 147 in single-member constituencies, by plurality; 245 in multi-member constituencies, by national proportional representation; 8 in multi-member abroad constituencies, by constituency proportional representation. For Italian residents, each house members are elected by single ballots, including the constituency candidate and his supporting party lists. In each single-member constituency the deputy/senator is elected on a plurality basis, while the seats in
