Abstract
In 1961, the 6-founding members of the EEC were confronted with the issue of expansion of the European Union (previously called as EEC). Prime Minister Harold Mac Millan announced that his government wished to join the Community and triggered the application of several other European countries. Since then, the negotiations for Britain to a part of the union has through a difficult phase. In his study of Britain's international policy, David Reynolds considered the membership of the EEC to be the most profound revolution in British foreign policy in the twentieth century.
