A Sunday Business Post/Red C poll suggests that support for Sinn Féin has dropped since the fiscal treaty campaign.

The poll indicates that Sinn Féin has dropped 3 points to 16%, though the party still remains well ahead of its general election result.

The poll, to be published in tomorrow's newspaper, shows that Fine Gael support is up 2 points to 32%, while support for Labour and Fianna Fáil remains unchanged at 15% and 18%.

Independent TDs and smaller parties in the Dáil Technical Group will also be relieved with the results showing support up 1 point to 19%.

Despite the group being at the centre of the political storm over the tax affairs of Independent TD Mick Wallace they remained untouched by the fallout.
