A non-binding referendum on the Single European Act was held in Denmark on 27 February 1986.[1] It was approved by 56.2% of voters,[2] with a voter participation of 75.4%.[3]
The referendum was held by the government of the Prime Minister of Denmark, Poul Schlüter. The government was in favour of Denmark ratifying the Single European Act, but a majority in parliament was against it.[2] The referendum was the last Europe-related referendum in which parties such as the Social Democrats and the Social Liberal Party recommended against ratification.
