Only Irish citizens are entitled to vote at referendums, in accordance with Article 47.3 of the Constitution. I have no plans to seek to amend the Constitution to give the right to vote in referendums to any other persons.
British citizens, who are ordinarily resident in the State and are 18 years or older, may vote at Dáil, European Parliament and local elections if they are entered in the register of electors. For future European elections, the specific impacts of the United Kingdom's exit from the European Union on European citizenship and the right to vote at elections to the European Parliament will ultimately be a matter to be determined within the negotiating process that has commenced between the United Kingdom and the European Union under Article 50 of the Treaty. As these negotiations have only recently commenced, it is not possible, at this point in time, to state what arrangements will apply into the future between the United Kingdom and the European Union in the matter of European citizenship and the rights pertaining thereto.
