Which non-EU microstate is a neighbour of the country which held an immigration referendum in February 2014?
Switzerland–European Union relations The relations between Switzerland and the European Union (EU) are framed by a series of bilateral treaties whereby the Swiss Confederation has adopted various provisions of European Union law in order to participate in the Union's single market. All but one (the microstate Liechtenstein) of Switzerland's neighbouring countries are EU member states.
Referendums related to the European Union The United Kingdom is the only EU member state to have held referendums on the issue of continued membership of the European Union and its antecedent organisation, the European Communities. In the first referendum in 1975, continued membership of what was then the European Communities (which included the European Economic Community, often referred to as the "Common Market" in the UK) was approved by 67.2% of voters, while in its second referendum in 2016 voters voted by 51.9% to leave the European Union.
