The EEC stands for the European Economic Community which was founded in 1957.
West Germany's economy grew 5% from 1951-64 whereas Britain's only grew half as much.
Britain originally had little interest in the EEC and they were involved in EFTA.
EFTA stood for the European Free Trade Association with Norway and Austria also being members of it.
Britain changed its mind on joining the EEC in the late 1950s but French President de Gaulle vetoed their application.
De Gaulle feared that Britain's commitment to Europe was too weak and he did not want to see any special trade agreements.
Britain had many special trade agreements with Commonwealth countries such as lamb with New Zealand.
Britain were again vetoed by de Gaulle regarding joining the EEC in 1965 because he feared that they were too close to the US.

Britain was firmly tied to NATO which stood for the North Atlantic Treaty Organisation.
Britain was also firmly tied to the US and the UK became heavily involved in the Korean War.
