In 1975, a national referendum was held on whether the United Kingdom should maintain its membership of the European Economic Community (EEC), now the European Union. This is the only example the UK has of a national referendum. The date set for the referendum was June 5th, 1975.
The question on the paper was: “Do you think that the United Kingdom should stay in the European Community (The Common Market)?”
