Donegal Sinn Féin TDs Pádraig Mac Lochlainn and Pearse Doherty have welcomed the Yes vote in both Donegal constituencies for Marriage Equality.
The Yes campaign celebrate at the count centre in Bonagee.
They said they wanted to congratulate the Yes Equality Donegal campaign for their tireless work over recent months.
"They brought a vibrancy and enthusiasm to this Marriage Equality Referendum that clearly won hearts and minds across Donegal.
"The levels of voter registration by young people in Donegal were unprecedented and the sight of so many of our emigrants returning home to vote was powerful.
"We also want to thank our fellow Donegal Sinn Féin members who put up posters, knocked on so many doors and delivered thousands of leaflets to homes across the county".
"We are delighted that Donegal has added our Yes to the big Yes from the Irish people.
"Ireland is now the only country or state in the world that has voted for Marriage Equality. This is a massive milestone in our history and one to be built on. In particular, the campaign for Marriage Equality will continue in the Six Counties. No one should fear Equality".
