supports: The euro (sign: €; code: EUR) is the official currency of the eurozone, which consists of 19 of the member states of the European Union: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. The currency is also officially used by the institutions of the European Union and four other European countries, as well as unilaterally by two others, and is consequently used daily by some 337 million Europeans . Outside of Europe, a number of overseas territories of EU members also use the euro as their currency. An electoral alliance may take the form of a bipartisan electoral agreement, electoral agreement, electoral coalition or electoral bloc. It is an association of political parties or individuals that exists solely to stand in elections. Each of the parties within the alliance has its own policies but chooses temporarily to put aside differences in favour of common goals and ideology. On occasion, an electoral alliance may be formed by parties with very different policy goals, which agree to pool resources to stop a particular candidate or party from gaining power. The European Commission (EC) is an institution of the European Union, responsible for proposing legislation, implementing decisions, upholding the EU treaties and managing the day-to-day business of the EU. Commissioners swear an oath at the European Court of Justice in Luxembourg, pledging to respect the treaties and to be completely independent in carrying out their duties during their mandate. A coalition is a pact or treaty among individuals or groups, during which they cooperate in joint action, each in their own self-interest, joining forces together for a common cause. This alliance may be temporary or a matter of convenience. A coalition thus differs from a more formal covenant. Possibly described as a joining of 'factions', usually those with overlapping interests rather than opposing. The President of the Council of Ministers of the Italian Republic (Italian: "Presidente del Consiglio dei ministri della Repubblica Italiana"), commonly referred to in Italy as Presidente del Consiglio and known in English as the Prime Minister of Italy, is the head of government of the Italian Republic. The office of Prime Minister is established by Articles 92 through to 96 of the Constitution of Italy. The Prime Minister is appointed by the President of the Republic after each general election and must have the confidence of the Parliament of Italy to stay in office. The President of the European Commission is the head of the European Commission (the executive branch of the :European Union) and therefore the most powerful officeholder in the EU, (loosely) analogous to the role of a country's Prime-Minister / Head of Government (as opposed to the separate role of President of the European Council, who could be seen as the European Union's Head of State)  although, unlike a national head of government, the President of the Commission does not have any authority other than as defined by the Treaties, does not determine foreign policy, command troops or raise taxes. The President of the Commission is responsible for allocating portfolios to members of the Commission and can reshuffle or dismiss them if needed. They determine the Commission's policy agenda and all the legislative proposals it produces (the Commission is the only body that can propose EU laws). The Union ( Italian : L'Unione ) was an heterogenous centre - left political and electoral alliance of political parties in Italy . The Union was led by Romano Prodi , Prime Minister of Italy from April 2006 to April 2008 , and former President of the European Commission . The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency. The Constitution of the Italian Republic was enacted by the Constituent Assembly on 22 December 1947, with 453 votes in favour and 62 against. The text, which has since been amended 15 times, was promulgated in the extraordinary edition of Gazzetta Ufficiale No. 298 on 27 December 1947. The Constituent Assembly was elected by universal suffrage on 2 June 1946, at the same time as a referendum on the abolition of the monarchy. The Constitution came into force on 1 January 1948, one century after the Statuto Albertino had been enacted. Although the latter remained in force after Benito Mussolini's March on Rome in 1922, it had become devoid of substantive value. Bologna (;  ) is the largest city (and the capital) of the Emilia-Romagna Region in Northern Italy. It is the seventh most populous city in Italy, located in the heart of a metropolitan area (officially recognized by the Italian government as a "città metropolitana") of about one million. The University of Bologna (UNIBO), founded in 1088, was the first university and is the oldest in the world. Romano Prodi, (born 9 August 1939) is an Italian former politician and economist. He twice served as the Prime Minister of Italy, from 17 May 1996 to 21 October 1998 and from 17 May 2006 to 8 May 2008. He was also the tenth President of the European Commission from 1999 to 2004. He is nicknamed "Il Professore" (The Professor) due to his occupation as professor of Economics at the University of Bologna. The European Council "(French: Conseil européen)", charged with defining the EU's overall political direction and priorities, is the institution of the European Union (EU) that comprises the heads of state or government of the member states, along with the President of the European Council and the President of the European Commission. The High Representative of the Union for Foreign Affairs and Security Policy also takes part in its meetings. Established as an informal summit in 1975, the European Council was formalised as an institution in 2009 upon the entry into force of the Treaty of Lisbon. Its current President is Donald Tusk. A head of state (or chief of state) is the public persona that officially represents the national unity and legitimacy of a sovereign state. In developing the current Constitution of France (1958), former French president Charles de Gaulle said the head of state should embody "the spirit of the nation" (""). In some countries, typically those with parliamentary governments, the head of state is a ceremonial figurehead that does not actually guide day-to-day government activities and may not even be empowered to exercise any kind of political authority (e.g., Queen Elizabeth II in the United Kingdom). In other countries, the head of state is also the head of government, such as in the U.S., where the president is both a public figurehead and the actual highest ranking political leader who, in practice, oversees the executive branch. Head of government is a generic term used for either the highest or second highest official in the executive branch of a sovereign state, a federated state, or a self-governing colony, (commonly referred to as countries, nations or nation-states) who often presides over a cabinet, a group of ministers or secretaries who lead executive departments. The term "head of government" is often differentiated from the term "head of state", (e.g. as in article 7 of the Vienna Convention on the Law of Treaties, article 1 of the Convention on the Prevention and Punishment of Crimes against Internationally Protected Persons, including Diplomatic Agents and the United Nations protocol list), as they may be separate positions, individuals, and/or roles depending on the country.
