[1][2] The main economic reason that Denmark joined the European Communities was because it wanted to safeguard its agricultural exports to the United Kingdom.

[4] However, the then President of France Charles de Gaulle vetoed British membership, and Denmark did not wish to join the EC without the United Kingdom.

[5] After much negotiation, and following a change in the French presidency, Denmark, Ireland and the United Kingdom eventually joined the European Communities on 1 January 1973.

[9] The EC became accepted and appreciated in Denmark, and an overwhelming majority of the Danish population supported the Single European Act in 1986.

[15] In February 2013, Denmark and the European Union reached an agreement on a seven-year budget, to approve the Danish demand.

In July 2011, Denmark reinforced its borders with Germany by stationing more officers, in an effort to halt the flow of illegal goods.

Most of the large political parties in Denmark favour the introduction of the euro, and the idea of a second referendum has been suggested several times since 2000.
