A new poll out tomorrow shows that voters are set to pass the European Fiscal Treaty at the end of May.
However the Sunday Business Post Red C survey does show a small drop in support for the 'Yes' side since last month.
This latest poll shows that, while there is still substantial opposition to the treaty, some 47% of voters say they will vote in favor of it.
A further 35% claim they will vote against it, while 18% say they are still undecided.
When the undecideds are excluded the 'Yes' lead the 'No' by 58% to 42%.
This is a small change from last month, showing a 2% gain for the 'No' side, but it comes as the main government parties prepare to launch their campaign for a 'Yes' vote next week.
