Labour faces an outside chance of losing its two seats in the European Parliament to the Green Party.
That's according to the latest opinion poll, which puts the Greens in contention for seats in Dublin and Ireland South.
The most striking finding of the Irish Times poll is that Grace O'Sullivan could be in contention to challenge Fine Gael's Deirdre Clune for the fourth seat in Ireland south.
Fianna Fáil's Brian Crowley will win easily on 31 per cent, while Sinn Féín's Liadh Ni Riada is on 19. Fine Gael's Sean Kelly has just 13, but appears set to do well on Mr Crowley's transfers.
That leaves the final seat between Deirdre Clune on 8, her FG colleague Simon Harris on 7, and the Greens' Grace O'Sullivan on 7.
But the poll says Deputy Harris will fail to pick up many transfers, with no Leinster candidates from the major parties - and so it's O'Sullivan wbo could be the biggest rival to Senator Clune.
In Dublin, Sinn Féin's Lynn Boylan and Fine Gael's Brian Hayes are on 23 and 22 per cent - with the final seat still up for grabs,
Fianna fail's Mary Fitzpatrick has 12, ahead of the Greens' Eamon RYan on 10, and Labour's Emer Costello on 9.
The independent Nessa Childers has 8, ahead of People BEfore Profit's Brid Smith on 7 and Paul Murphy of the SOcialist Party on 6.
Finally in Midlands North-West, Fine Gael's Mairead McGuinness tops the poll on 18, while Sinn Féin's Matt Carthy should also be elected with 15 per cent.
FIanna Fail's Pat the Cope Gallagher has 12 per cent, tied with independent Luke Ming Flanagan - while another independent, Marian Harkin, is on 10.
FIne Gael's JIm Higgins has 9, while Labour's Lorraine Higgins and Thomas Byrne of Fianna Fail are on 8 per cent each.
500 voters were sampled in each constituency between Thursday and Saturday of last week.
