Nine News: David Davin-Power, Political Correspondent, reports that Fine Gael says the referendum is a defining moment for this country
46% of those polled are in favour of the Treaty, this is an 8 point fall since the last Irish Times/TNS mrbi poll in May.
There has been a seven point increase in the number of undecided voters, bringing the undecided to one quarter of voters.
The Irish Times poll shows that 29% say they will vote No. This is an increase of just one point.
The margins may worry some because at this point before the first Lisbon Referendum, the 'yes' side was even further ahead and went on to lose.
There are fewer undecided voters this time round. Both sides will have to make a determined effort to win them over before 2 October.
