Europe’s leaders hold their breath as France votes on the Union’s constitution.Ballots in this crucial referendum are already being cast in French overseas territories. The mainlaind goes to the polls tomorrow with a real possibility the electorate could reject the charter. If so, the whole project will be thrown into question. Between now and 10pm Central European Time Sunday, 41.8 million French will get to have their say. We will be bringing you exit polls and the final result on EuroNews as soon as they come through. Voting will be partly by traditional ballot, and partly via electronic machines. So far nine countries have delivered their verdict on the Constitution, either by parliamentary debate as in Germany on Friday, or by referendum. And all have effectively ratified it. But all 25 of the European Union’s member states need to approve it before it can become law. The last opinion poll to put France’s Yes camp ahead was on May 9. Since then, 15 consecutive surveys indicate the referendum will be rejected.
