The Gibraltar sovereignty referendum of 1967 was held on 10 September 1967, in which Gibraltarian citizens were asked whether they wished to pass under Spanish sovereignty, with Gibraltarians keeping their British citizenship and a special status for Gibraltar within Spain; or remain under British sovereignty, with its own self-governing institutions.[1]

Resolution 2353 (XXII) was supported by seventy-three countries (mainly Latin American, Arab, African and Eastern European countries),[6] rejected by nineteen (United Kingdom and the countries of the Commonwealth of Nations), while twenty-seven countries abstained (Western Europe and the United States).
