The United Kingdom European Union membership referendum held on 23 June 2016, which resulted in 51.9% of votes being cast in favour of exiting the EU, occurred during the electoral campaign leading to the French presidential election of 2017. Following the referendum result, Front National Leader Marine Le Pen promised a French referendum on EU membership if she were to win the presidential election. Former President François Hollande met with politicians including Le Pen in the aftermath of the vote and rejected her proposal for a referendum. Fellow 2017 candidate Nicolas Dupont-Aignan of Debout la France also advocated for a referendum. François Asselineau's Popular Republican Union instead advocate a unilateral withdrawal of the EU using article 50 of the Treaty of Lisbon.
