Referendum Held on British Membership of the European Community.

The United Kingdom European Communities Membership Referendum was held on June 5, 1975, to determine whether the UK should remain a member of the European Economic Community (EEC)—commonly referred to as the “Common Market.” The UK had joined the EEC in 1973, and this referendum was the first nationwide plebiscite in the country’s history.

Scotland’s Results:

-	Yes (to remain in the EEC): 1,332,286 votes
-	No (to leave the EEC): 948,039 votes
-	Turnout: 61%
-	Majorities Against:
-	Western Isles (Na h-Eileanan an Iar)
-	Shetland

These two areas voted “No” primarily due to concerns over fishing rights and local economic impacts.

UK-Wide Result:

-	Yes: 67.2%
-	No: 32.8%
-	Turnout: 64%

The strong national result in favor of remaining in the EEC was interpreted as a public endorsement of continued European membership—an issue that would remain contentious and re-emerge decades later in the 2016 Brexit referendum.
