Early indications for the European elections show that in the Dublin constituency Fine Gael's Gay Mitchell is currently heading the poll with just over 22% of the vote.
Eoin Ryan is the leading Fianna Fáil candidate, with 16%, compared to just 8% for Royston Brady.
Labour's Proinsias de Rossa is on almost 13%, ahead of running mate Ivana Bacik on 10%.
The final seat, according to the tallies, will be between Sinn Féin's Mary Lou McDonald on 12% and Patricia McKenna of the Greens on 10%.
South constituency
In the South constituency, tallies show Simon Coveney of Fine Gael ahead of Brian Crowley of Fianna Fáil at the top of the poll.
The third seat will be between Kathy Sinnott and Gerry Collins, with most tallies showing her ahead at this stage.
North West constituency
In the North West constituency, the big surprise is the strong performance of Sinn Féin's Pearse Doherty, although he would still need substantial transfers to take a seat.
Fianna Fáil's two candidates, Jim McDaid and Sean O Neachtain, appear to be neck and neck while Marian Harkin is ahead of the sitting Independent, Dana Rosemary Scallon. Tallies indicate she could take over 60% of the vote in her home base of Sligo.
Jim Higgins is the leading Fine Gael candidate, and seems to be in a strong position to take a seat.
East constituency
In the East constituency, Fine Gael's Mairead McGuinness is out-polling her running mate, Avril Doyle.
It is now looking unlikely at this stage that Fine Gael will take two seats in this area.
Liam Aylward of Fianna Fáil and Labour's Peter Cassells look likely to take the other two seats.
The results of the European Parliament elections cannot be announced until polls close throughout other EU member states tomorrow evening.
