General

The 1948 Constitution of Italy established a bicameral parliament (Parlamento), consisting of a Chamber of Deputies (Camera dei Deputati) and a Senate (Senato della Repubblica), a separate judiciary, and an executive branch composed of a Council of Ministers (Consiglio dei ministri), headed by the prime minister (Presidente del consiglio dei ministri). Administratively the country is divided into 15 regions and five autonomous regions, which also have parliaments and governments.

The President of the Italian Republic (Presidente della Repubblica) is elected for seven years by the parliament sitting jointly with a small number of regional delegates. The president nominates the prime minister, who proposes the other ministers (formally named by the president). The Council of Ministers must obtain a confidence vote from both houses of Parliament. Legislative bills may originate in either house and must be passed by a majority in both.

The houses of the bicameral parliament, are popularly and directly elected through a complex electoral system (latest amendment in 2005) which combines proportional representation with a majority prize for the largest coalition (Chamber). All Italian citizens older than 18 can vote. However, to vote for the senate, the voter must be at least 25 or older. The electoral system in the Senate is based upon regional representation. During the elections in 2006, the two competing coalitions were separated by few thousand votes, and in the Chamber the centre-left coalition (L'Unione) got 345 Deputies against 277 for the centre-right one (Casa delle Libertà), while in the Senate, l'Ulivo got only two Senators more than absolute majority. The Chamber of Deputies has 630 members and the Senate 315 elected senators; in addition, the Senate includes former presidents and appointed senators for life (no more than five) by the President of the Republic according to special constitutional provisions. As of May 15, 2006, there are seven life senators (of which three are former Presidents). Both houses are elected for a maximum of five years, but both may be dissolved by the President before the expiration of their normal term if the Parliament is unable to elect a stable government. In the post war history, this has happened in 1972, 1976, 1979, 1983, 1994 and 1996.

A peculiarity of the Italian Parliament is the representation given to Italian citizens permanently living abroad (about 2.7 million people). Among the 630 Deputies and the 315 Senators there are respectively 12 and 6 elected in four distinct foreign constituencies. Those members of Parliament were elected for the first time in April 2006 and they have the same rights as members elected in Italy.
