Campaigning in the United Kingdom European Union membership referendum, 2016

Campaigning in the United Kingdom European Union membership referendum began unofficially on 20 February 2016 when Prime Minister David Cameron formally announced under the terms of the European Union Referendum Act 2015 that a referendum would be held on the issue of the United Kingdom's membership of the European Union. The official campaign period for the 2016 referendum ran from 15 April 2016 until the day of the poll on 23 June 2016.

At the close of applications on 31 March only Britain Stronger in Europe had applied to the Electoral Commission for the official "remain" designation. Three competing applications were submitted for the official "leave" designation. The Electoral Commission announced the designated campaign groups for the leave and remain sides on 13 April 2016, two days before the official ten-week campaign period began.

The Remain Campaign was led by Britain Stronger in Europe, a cross-party lobbying group that was declared as the official "Remain" campaign for the referendum by the Electoral Commission. However there were a number of other groups that were involved in leading more specialist campaigns.

Examples of leaflets used by the remain groups can be found on the LSE Library's collection of referendum leaflets.

Vote Leave was the lead organisation campaigning for a leave vote in the referendum. On 13 April 2016, Vote Leave was designated by the Electoral Commission as the official campaign in favour of leaving the European Union for the United Kingdom European Union membership referendum. Vote Leave was created in October 2015 and was a cross-party campaign, including members of Parliament from Conservatives, Labour, and UKIP.
