Support for both Fianna Fáil and Fine Gael has increased, an opinion poll for the Sunday Times suggests.
The survey of voters by Behaviour and Attitudes also suggests a small drop in support for Sinn Féin, unaligned independents and Labour.
This poll was, for the most part, carried in the days before last Tuesday's Budget. Voters were asked, over the 12 days up to Wednesday last, who they would support if there was a general election tomorrow.
The poll shows the two biggest parties, Fine Gael and Fianna Fáil, fared best.
Fianna Fáil are up two points on 30%, while Fine Gael support climbed three points to 26%.
Sinn Féin are down one point to 17% and there is a two-point drop for Labour which now stands at 5%.
A one-point drop for the unaligned Independents leaves them on 11% and the Independent Alliance is unchanged on 4%.
The AAA-PBP drop two points to stand at 2%. The Greens are also on 2%.
Support for the Social Democrats, who have two TDs, is measured at below 1% in this poll.
The Workers Party are on 3% and Renua are on 1%.
