About this election
At a glance
On 3 December 2015 Denmark held a referendum on whether to convert its sweeping opt-out from EU justice and home affairs into a flexible "opt-in" model, under which Denmark could choose, case by case, to participate in individual EU measures. Voters rejected the proposal by 53.11% to 46.89%, choosing to keep the full opt-out — a result widely read as a defeat for the political establishment and a reflection of deep Euroscepticism among Danish voters.
