Palazzo Montecitorio, seat of the Italian Chamber of Deputies.
After the resignation of Silvio Berlusconi on 12 November 2011, economist Mario Monti has been appointed as a technocratic Prime Minister. The Italy's four major political parties are the People of Freedom, the Democratic Party, the Northern League and the Union of Christian and Centre Democrats (UDC). During the 2008 general elections these four parties won 589 out of 630 seats available in the Chamber of Deputies and 293 out of 315 seats available in the Senate of the Republic.
Most of the remaining seats were won by minor parties that only contest election in one part of Italy, like the South Tyrolean People's Party and the Movement for Autonomies. However, during the last 3 years, a so-called "Third Pole" emerged, merging the Christian Democrats of UDC with some dissident MPs coming from Mr. Berlusconi's cabinet.
A peculiarity of the Italian Parliament is the representation given to Italian citizens permanently living abroad: 12 Deputies and 6 Senators elected in four distinct overseas constituencies. In addition, the Italian Senate is characterized also by a small number of senators for life, appointed by the President "for outstanding patriotic merits in the social, scientific, artistic or literary field". Former Presidents of the Republic are ex officio life senators.

The Supreme Court of Cassation.
The Italian judicial system is based on Roman law modified by the Napoleonic code and later statutes. The Supreme Court of Cassation is the highest court in Italy for both criminal and civil appeal cases. The Constitutional Court of Italy (Corte Costituzionale) rules on the conformity of laws with the constitution and is a post–World War II innovation. Since their appearance in the middle of the 19th century, Italian organized crime and criminal organizations have infiltrated the social and economic life of many regions in Southern Italy, the most notorious of which being the Sicilian Mafia, which would later expand into some foreign countries including the United States. The Mafia receipts may reach 9%[90][91] of Italy's GDP.[92]
A 2009 report identified 610 comuni which have a strong Mafia presence, where 13 million Italians live and 14.6% of the Italian GDP is produced.[93][94] The Calabrian 'Ndrangheta, nowadays probably the most powerful crime syndicate of Italy, accounts alone for 3% of the country's GDP.[95] However, at 0.013 per 1,000 people, Italy has only the 47th highest murder rate[96] (in a group of 62 countries) and the 43rd highest number of rapes per 1,000 people in the world (in a group of 65 countries), relatively low figures among developed countries.

Italy is a founding member of the European Community, now the European Union (EU), and of the North Atlantic Treaty Organization (NATO). Italy was admitted to the United Nations in 1955, and it is a member and strong supporter of a wide number of international organizations, such as the Organisation for Economic Co-operation and Development (OECD), the General Agreement on Tariffs and Trade/World Trade Organization (GATT/WTO), the Organization for Security and Co-operation in Europe (OSCE), the Council of Europe, and the Central European Initiative. Its recent turns in the rotating presidency of international organisations include the Conference for Security and Co-operation in Europe (CSCE), the forerunner of the OSCE, in 1994; G8; and the EU in 2009 and from July to December 2003.
Italy strongly supports multilateral international politics, endorsing the United Nations and its international security activities. Italy deployed troops in support of UN peacekeeping missions in Somalia, Mozambique, and East Timor and provides support for NATO and UN operations in Bosnia, Kosovo and Albania. Italy deployed over 2,000 troops in Afghanistan in support of Operation Enduring Freedom (OEF) from February 2003. Italy still supports international efforts to reconstruct and stabilize Iraq, but
