Fianna Fail and Fine Gael are neck-and-neck in political support for the first time since 2008.
That is according to a new opinion poll due to be published in tomorrow's Sunday Business Post.
Both parties are on 26 per cent support.
The Red C survey of over 1,000 voters nationwide was carried out last Monday, Tuesday and Wednesday, as the Alan Shatter penalty points controversy was in full flight.
It shows that Fine Gael has dropped two points since last month while Fianna Fail gain a point, leaving the two parties tied.
Sinn Fein is on 16 per cent, while Labour is still struggling to satisfy the electorate with just 11 per cent support.
Independents and others gain one point and are on 21 per cent.
It is the first drop in Fine Gael support for over six months, while Fine Gael and Labour support together has fallen away by some 18 per cent since the general election in 2011.
