<P> In 1957, six core states founded the EU's predecessor, the European Economic Community (Belgium, France, Italy, Luxembourg, the Netherlands and West Germany). The remaining states have acceded in subsequent enlargements . On 1 July 2013, Croatia became the newest member state of the EU . To accede, a state must fulfill the economic and political requirements known as the Copenhagen criteria, which require a candidate to have a democratic, free - market government together with the corresponding freedoms and institutions, and respect for the rule of law . Enlargement of the Union is also contingent upon the consent of all existing members and the candidate's adoption of the existing body of EU law, known as the acquis communautaire . </P> <P> There is disparity in the size, wealth and political system of member states, but all have de jure equal rights . In practice, certain states are considerably more attractive than others . While in some areas majority voting takes place where larger states have more votes than smaller ones, smaller states have disproportional representation compared to their population . No member state has withdrawn or been suspended from the EU, though some dependent territories or semi-autonomous areas have left . In June 2016, the United Kingdom held a referendum on membership of the EU, resulting in 51.89% of votes cast, being in favour of leaving . Prime Minister Theresa May invoked Article 50 on 29 March 2017 to formally initiate the withdrawal process . </P> <Table> <Tr> <Th> Country name </Th> <Th> Native name </Th> <Th> Arms </Th> <Th> Flag </Th> <Th> Capital </Th> <Th> Accession </Th> <Th> Population </Th> <Th> Area (km2) </Th> <Th> GDP (PPP) (millions of US $) </Th> <Th> GDP per cap .
