Question

how are countries in the European union linked

Answer 1

1)They all have ratified the Lisbon Treaty which is the newest treaty that defines EU's common institutions - the European Parliament (legislative power), the European Commission (Executive power), the Court of Justice of the EU (judiciary power), European Central Bank, Council of Ministers and the European Council.

2) They share a single market, ensuring the free flow of capital, goods, services and people. 17 of them share a single currency - the euro. More member countries are expected to join the Eurozone as soon as they fulfill the Maastricht criteria (budget deficit, external debt, inflation and other limits).

2) 25 of them (except the newest 2 members, but that will change) according to Schengen Agreement have abolished border controls in between the member countries.
