1975 United Kingdom European Communities membership referendum

1975 United Kingdom European Communities membership referendum was the first major national plebiscite in the history of the United Kingdom. Held on 5 June 1975, it asked voters whether the United Kingdom should remain a member of the European Communities, which it had joined under the Conservative government of Edward Heath in 1973. The result was a decisive vote in favour of continued membership, with 67.2% of voters supporting a "Yes" and a turnout of 64.5%. The referendum was called by the Labour government of Harold Wilson to resolve deep divisions within his party and the country over European integration.

Background

The United Kingdom had initially sought to join the European Economic Community in the 1960s, but its applications were vetoed by Charles de Gaulle of France. Success finally came under Prime Minister Edward Heath, with the Treaty of Accession 1972 leading to membership on 1 January 1973. The Labour Party, then in opposition, was deeply split, with figures like Tony Benn and Michael Foot opposing membership while others, such as Roy Jenkins, were strong proponents. Upon returning to power in the February 1974 general election, Harold Wilson renegotiated the terms of membership, securing changes to the Common Agricultural Policy and Britain's budget contribution. The Labour government then promised a referendum to settle the issue, passing the necessary legislation through the Parliament of the United Kingdom.

Campaign

The official "Yes" campaign, Britain in Europe, was a broad coalition led by senior figures from all major parties, including Harold Wilson, Edward Heath, Jeremy Thorpe of the Liberal Party, and Roy Jenkins. It was supported by much of the British press, including The Times and The Economist, and argued that membership was vital for economic prosperity, international trade, and global influence. The "No" campaign, the National Referendum Campaign, was led by left-wing Labour figures like Tony Benn and Michael Foot, alongside Enoch Powell and some Conservative Eurosceptics. They framed the European Communities as a threat to Parliamentary sovereignty, a drain on the Treasury, and a cause of rising food prices. High-profile debates, such as those on BBC's *Nationwide*, were a key feature of the campaign.

Results

The referendum was held across the United Kingdom, including Gibraltar, on 5 June 1975. The result was overwhelmingly in favour of remaining in the European Communities. The national "Yes" vote was 17,378,581 (67.2%), while the "No" vote was 8,470,073 (32.8%). Turnout was 64.5% of the 40 million eligible voters. Every county and region voted "Yes", with the strongest support in Southern England and the weakest in the Outer Hebrides and Shetland. In Gibraltar, the vote was 95% in favour. The clear result provided a strong, albeit temporary, mandate for continued British participation in the European project.

Aftermath

The immediate aftermath saw a period of political calm on the European question. Harold Wilson's government was strengthened, having united a divided Cabinet under the referendum result. Pro-European figures like Roy Jenkins and Shirley Williams saw their influence grow within the Labour Party. However, the underlying tensions were not resolved. Economic difficulties in the late 1970s, including the Winter of Discontent, were sometimes blamed on EC policies by critics. The election of Margaret Thatcher in 1979 began a new era of more assertive British negotiation within the European Communities, exemplified by the UK rebate secured at the Fontainebleau Summit.

Legacy

The 1975 referendum is a pivotal event in the history of British Euroscepticism. It established the precedent of using a referendum to decide major constitutional issues, a path followed decades later for the 2016 United Kingdom European Union membership referendum. The arguments over sovereignty, economics, and national identity first fully aired in 1975 resurfaced continuously in British politics, influencing debates over the Maastricht Treaty and the creation of the European Union. The referendum's result was ultimately overturned by the 2016 vote, leading to Brexit and the UK's departure from the European Union in 2020. The 1975 campaign is often studied as a landmark in British political history and the use of direct democracy in the United Kingdom.
