Marian Harkin has been returned to the European Parliament after a ballot recheck in the Midlands North West constituency.
The Independent candidate is the final MEP to be elected in Ireland,and also the last declared winner across Europe.
It means that out of 11 Irish seats - four have been filled by Fine Gael, three by Sinn Féin, one by Fianna Fáil and three by Independents.
After four days of counting and 18 hours of a recheck, Fianna Fáil's Pat the Cope Gallagher conceded defeat at 4 O'clock this morning, securing Marian Harkin's election to the European Parliament.
Hers is the 11th and final seat to be filled in Ireland.
Harkin was the fourth candidate to get over the line in Midlands North West, joining Independent Luke Ming Flanagan, Fine Gael's Mairead McGuinness and Sinn Féin newcomer Matt Carthy.

After a marathon five day count and a recheck, Marian Harkin thanked her team of supporters for all their hard work.
Luke Ming Flanagan was the first to be elected in the constituency on Monday.
Meanwhile, Sinn Féin's Matt Carthy and Fine Gael's Mairead McGuinness took the second and third seats.
Elections wrap
In the South, Fine Gael's three candidate approach paid off with former GAA President Sean Kelly and Cork Senator Deirdre Clune both elected, coming in behind poll topper Brian Crowley and Sinn Féin's Liadh Ní Ríada.
In Dublin, Sinn Féin's strong performance was underlined by an emphatic win by Lynn Boylan - who was joined after a recheck by Independent Nessa Childers and Fine Gael's Brian Hayes.
Meanwhile, in the local elections Fine Gael's Mary Fayne took the last council seat in Ireland - excluding the re-run in Monaghan next week.
