No minimum turnout in binding EU referendum
Polls open at 2pm on Friday, and close at 2pm on Saturday. Unconfirmed results should be available almost immediately. There is no minimum turnout needed for the referendum to be declared valid, but the vote is binding: if a majority of people vote "Yes" to joining the EU, there will be no need for the parliament to ratify accession. In the event of a "No" vote, the government can ask the President to hold a second referendum in two years' time. The latest opinion polls suggest around 75 percent will vote in favour of accession, although a low turnout could reduce that margin considerably.
