Voters on both sides of the Irish Sea have been going to the polls.
In Britain, Tony Blair, Conservative leader William Hague and Liberal Democrat leader Charles Kennedy were among the first out to cast their votes.
In the North, voting is reported to be heavy in an election that could ultimately decide the future of the Good Friday Agreement.
Here, however, turnout is slow for the three referendums.
The general consensus on the referendums was that the turnout would be low.
So far, this is proving to be very much the case.
Returning officers across the 41 constituencies are reporting voting as slow, very slow or extremely slow.
So far, in Dublin, it is estimated that between 3 and 5% of the electorate have cast their votes.
In the midlands, 4% have turned up so far and in the south around 5% but the polls stay open until 9 o'clock tonight and traditionally the busiest time is in the evening with the work force returning home.
Almost 2.9 million people are entitled to vote in these referendums on the Nice Treaty, death penalty and international criminal court.
