PEOPLE have until 23:59 BST on Tuesday 7 June to register to be able to vote in the referendum on whether the UK stays in the European Union or leaves.
Registering online should take about five minutes. People may need their National Insurance number, or passport number if a UK citizen living abroad.
The Electoral Commission said it was the "last chance" for people to take part in the 23 June referendum.
