Who could vote in the EU referendum? British, Irish and Commonwealth citizens who live in the UK, along with Britons who have lived abroad for less than 15 years, were eligible to vote. As with other elections, only people aged 18 and over could cast their vote in the nationwide referendum today. Young Scots aged 16 and 17 can vote in Scottish elections but they could not vote in the EU referendum because voters had to be at least 18.

Which Commonwealth citizens can vote? Commonwealth migrants from 54 states - including ­Australia, Canada, India, Pakistan and Nigeria - could join the electoral roll as long are they are residents in the UK. Unlike in general elections, Commonwealth citizens in Gibraltar were allowed to vote and have gone to the polls in the EU referendum.

Could British expats vote? To register as an overseas voter, British citizens must have been registered in a UK constituency less than 15 years ago. UK expats voted by post, by appointing someone to vote on their behalf or in person at their home polling station if they are visiting the UK. Two British expats last month lost their appeal to be able to vote in the referendum even though they have lived abroad more than 15 years.

Could European citizens vote? Citizens from other European countries - apart from Ireland, Malta and Cyprus - did not get to vote on whether the UK remains part of the EU. Malta and Cyprus are both Commonwealth countries.
