The European Union (EU) refers to an economic and political union comprising twenty seven member states mainly situated in Europe. A harmonized system of rule is applicable on all member states, where the states have agreed to operate as one, creating a single internal market. EU policies strive to ensure free flow of services, people, capital, and goods within the internal market place. They also emphasize on preserving common policies in trade, fisheries, agriculture and regional development, and enact laws relating to justice and home affairs. The EU consists of seven major decision-making bodies, which include institutions such as the EU court of justice, European court of auditors, the European council, the European commission, the European central bank, the European parliament, and the Council of the European Union.
