Independent candidate for the Irish presidency and one-time opinion poll-topper Sean Gallagher has conceded defeat to the Labour Party's Michael D Higgins.
Businessman Mr Gallagher, a former member and fundraiser for the Fianna Fail party, has accepted the veteran politician will be the country's ninth head of state.
"In the last hour I've called Michael D Higgins to congratulate him on his performance and his success in this election," Mr Gallagher said. "He will have my full support as president and I sincerely thank him for a positive campaign. His slogan stated that he would be a president to be proud of and I believe he will be that president."
Mr Higgins, 70, a former Labour Minister, looks set to take about 40% of the vote on the first count, to be confirmed at Dublin Castle later.
Mr Gallagher appears on course to finish second but has seen his support collapse from a high of 40% in last weekend's opinion polls to closer to 30% in the vote proper.
Eamon Gilmore, the country's deputy prime minister and Labour leader, said: "This is a good day for the Labour Party. Our nominee Michael D Higgins looks pretty certain that he will be elected the ninth president of Ireland."
Sinn Fein's Martin McGuinness looked set to take third place in the vote and secured a huge boost for his party by topping the poll in the Donegal North-East constituency.
Gerry Adams, his party's president, said the support would bring politics in Northern Ireland and the Republic closer. "I think what we have done is narrow the gap between politics in the north and the south," Mr Adams said.
Gay Mitchell, candidate for Government party Fine Gael in coalition with Labour, had a poor showing that left him vying with Senator David Norris, a former Trinity professor and Joycean scholar, for the fourth and fifth spots with a record seven candidates in the race.
The also-rans are Mary Davis, who headed the Irish division of Special Olympics, and Dana Rosemary Scallon, former Eurovision winner and Eurosceptic MEP.
