France, under de Gaulle's successor
Georges Pompidou, removed its opposition following the 1969 Hague EEC summit conference. This made the expansion of membership possible, providing for political convergence between the EEC and EFTA. After a long period of negotiations, expansion of the EC's membership was ratified by the member states' national parliaments, except in the case of France, where in April 1972 a referendum on EC enlargement was passed with a favorable vote of 68%. In Norway's referendum however, 53.5% of voters opposed the country's accession, and Prime Minister
Trygve Bratteli resigned following the defeat of his government. It was the second attempt by Norway to become a member, after being rejected by France in 1962 and again temporarily in 1967, but the first attempt at a referendum following a successful negotiation. The United Kingdom consulted its citizens directly only after joining the European Communities: following the British general election of October 1974, the Labour government of
Harold Wilson held a referendum to fulfill one of its campaign promises.
The non-binding referendum was held on 5 June 1975, some two and half years after the UK's accession. It was the first ever national referendum to be held in the UK, and the "yes" vote won by a landslide 67.23% on a 65% turnout with 66 out of the 68 local counting areas returning majority "yes" votes. ==Legal consequences==
