A poll conducted by RTE Television showed that nearly 70 percent of respondents voted to repeal the abortion ban, and another poll for The Irish Times was similar - showing 68 percent of those surveyed voted for repealing the eight amendment, against 32 percent who said abortions should still be banned in the country. RTE's exit poll showed a similar split on the vote, with an estimated 69.4% voting "Yes" and 30.6% voting "No", according to the exit poll.
Official counting of Friday's vote begins Saturday morning, and an official result will be announced Saturday afternoon.

Irish Prime Minister Leo Varadkar on Saturday hailed a resounding referendum majority in favour of overturning the abortion ban as the "culmination of a quiet revolution".
Abortions are only allowed in Northern Ireland if a woman's life is at risk or there is a permanent or serious risk to her physical or mental health.
The first vote I ever cast was in one of the six referendaums that Ireland has had on abortion.
It was also the tragic case of an Indian dentist, 31-year-old Savita Halappanavar, who died in Ireland in 2012, because of complications form a natural miscarriage after abortion was denied to her, that ignited the pro-choice campaign.
The result looks set to be another hammer blow to the Roman Catholic Church's authority in Ireland, coming three years after referendum voters backed legalising same-sex marriage by 62 percent.
"What Irish voters did yesterday is a tragedy of historic proportions", the Save The 8th group said. Amnesty International Ireland and the Abortion Rights Campaign, for instance, were required to return political grants of $150,000 and $25,000, respectively, to George Soros's Open Society Foundations.
