Support for both Fianna Fáil and Fine Gael has fallen according to the latest opinion poll.
The Sunday Business Post/Red C poll shows that support for Fianna Fáil is at 33 per cent while Fine Gael stands at 25 per cent.
Support for the Labour Party has increased by two points to 14 per cent, while the Progressive Democrats have doubled their support from two per cent to four per cent. Sinn Fein have dropped two points and the Greens remain unchanged.
The poll was carried out before the controversy which began on Thursday in relation to payments made to the Taoiseach, Bertie Ahern during the 1990s.
