The opening of boxes at the count centre in Letterkenny.
Donegal is the only constituency in the country looking at a No vote in the referendum, according to tallies.
Tallies from the opening of boxes in Donegal put the No vote on 52%.
With around 50 boxes left to be opened at the count at the Aura Leisure Centre in Letterkenny there is very little in it in Donegal, tallies suggest.
A Sinn Féin tally is giving a 52% No to a 48% Yes vote with more than 48,000 votes tallied.
An earlier break down with just over 17,000 votes tallied put the Yes vote ahead very narrowly at 50.4%.
That tally gave Inishowen a 55.8% No - 44.1 Yes, Letterkenny 50.9 Yes - 49% No, Donegal 52.9% Yes - 47% No, Glenties 51% No - 48.9 Yes, Stranorlar 52.3 Yes - 47.6% No.
The opening of boxes has resumed after a break with about 80% of them opened so far.
