A new opinion poll has placed Fianna Fail at the top of the popularity chart for the first time since the onset of the financial crisis almost five years ago.
The party gained 26% of support in the survey of 1,000 voters - one point ahead of Fine Gael.
The Ipsos MRBI poll was carried out on Monday and Tuesday, before the current coalition Government struck a deal with European banking chiefs over Ireland's outstanding debt burden.
Fine Gael and the Labour Party will hope the agreement to restructure the multi-billion debt with a longer payment period will give them a boost in public support.
In the poll conducted for the Irish Times, Sinn Fein garnered 18% support, Labour 10%, the Green Party 1% and others and independents 20%.
The figures do not include undecided voters. Around a third of those polled said they had not made their minds up, indicating that public opinion remains significantly fluid in regard to the main parties.
