Forty years ago, on 5 June 1975, Britain held its first referendum on whether the UK should stay or leave the European Community (Common Market). The majority voted Yes - 17,378,581 people (67.2 per cent) - to remain in Europe.
The Guardian’s analysis of the result included David Mckie’s Anatomy of a landslide in which he noted that Shetland and the Western Isles were the only areas in the country to vote No. The decisiveness of the Yes-vote ended a period of uncertainty while opening the way for a new French initiative for political unity in Europe.
A fullhearted decision was the Guardian’s verdict on the result, while a second editorial called for the European parliament to move to Brussels.
The anti-marketeers included Tony Benn and Enoch Powell, while Margaret Thatcher argued for staying in Europe.
