TANAISTE Eamon Gilmore has indicated sitting MEP Emer Costello will be the Labour Party's only candidate in next year's European elections.
Labour was understood to be desperately seeking a second candidate in order to salvage its Dublin seat in the European Parliament.
Party figures were looking at selecting a running mate as part of the overall strategy for next summer's elections. Mr Gilmore told the Herald he expects Labour to run just one candidate in each of the three European constituencies.
"My own thinking is that it is likely to be one candidate per constituency, unless there are geographic reasons why you might. I mean there are two four-seat constituencies now so there might be geographic considerations," he said.
Mr Gilmore said he didn't want to pre-empt the recommendation of an internal party committee, which is looking at the party's election strategy.
"I think the most likely scenario is one per constituency," he said.
In the capital, Mr Gilmore says the party will have one candidate, Ms Costello.
"It is a three-seater. There is a sitting MEP," he said.
A number of sitting politicians have been considered as the party prepares for a "dogfight" to hold on to Ms Costello's seat.
One party figure mooted as a potential running mate, Lord Mayor Oisin Quinn, last night ruled himself out of contention.
"It's not something on my radar, particularly with the work I have as mayor. So yes, I am happy to rule myself out," he said.
Senior party figures are becoming increasingly concerned about the prospect of losing the seat held for 12 years by former MEP Proinsias de Rossa.
Labour sources said Mr Quinn would provide significant transfer to Ms Costello given his high profile.
