An opinion poll released today indicates a majority of voters are as yet undecided on how they will vote in the upcoming Nice referendum.
The poll gives a slight edge to a "yes" vote in the upcoming referendum on the Nice Treaty.
The telephone survey of 939 people found nine percent did not intend to vote while 44 percent were undecided, Citigroup said.
The poll commissioned by Citigroup Inc found 29 percent would vote in favour of passing the EU's Nice Treaty, which was rejected last year, while 19 percent would vote "no."
"The poll suggests that a 'yes' vote is slightly more likely than a 'no' vote, but that the outcome is very uncertain," Citigroup said in a statement.
"In particular, the high level of undecided voters could swing the outcome either way."
The poll by Millward Brown IMS also found women were generally more sceptical or negative towards the treaty than men.
The Dáil is winding up a final two days of debate on the enabling legislation for the referendum, after which a date for the vote will be announced. It is expected in mid to late October.
The Nice Treaty must be ratified by all 15 existing EU members before the end of the year, or it will be scrapped.
The last opinion poll by the Market Research Bureau of Ireland, released in May before the general election, showed opinion drifting towards a "no" vote.
