The campaign was defined by women publicly sharing their painful experiences of leaving the country for procedures, a key reason why all but one of Ireland's 40 constituencies voted "Yes".

A woman casts her vote in Ireland's referendum on liberalizing abortion law, on Gola Island, Ireland, May 24, 2018. On Friday, Ireland will decide whether to repeal its Eighth Amendment and change its current abortion laws.

There are a lot of happy faces.

Speaking shortly after the result was confirmed, the country's prime minister Leo Varadkar said it marked "the day Ireland stepped out from under the last of our shadows and into the light".

Sinn Fein leader Mary Lou McDonald reacts with a member of the "Yes" campaign.

Irish voters - young and old, male and female, farming types and city-bred folk - endorsed expunging an abortion ban from their largely Catholic country's constitution by a two-to-one margin, referendum results compiled Saturday showed.

"A hundred years since women gained the right to vote, today we as a people have spoken", he said.

Officials say a final national result for Friday's referendum may not be declared until early Saturday evening.

Some have begun circulating the legislation they would pass if the amendment is repealed. Currently, abortions are illegal in the country, making Ireland's laws on abortion some of the most severe in the world. The group said on its website that Irish voters have created a "tragedy of historic proportions", but McGuirk said the vote must be respected.

Releasing a snippet on Instagram, with a full video on Youtube, Hozier opens by saying: "I just wanted to send on a wee video about this upcoming Friday. That would be wrong".

Voters will be asked if they want to repeal the eight amendment in the Irish constitution, the clause which effectively prohibits abortion by giving the mother and unborn child an equal right to life.

"Yes" campaigners like Coveney have argued that with over 3,000 women travelling to Britain each year for terminations and others ordering pills illegally online, abortion is already a reality in Ireland.

Ireland appeared to move away from its conservative Roman Catholic roots and embrace a more liberal view.

At Cambridge, however, the women's campaign said funding is dependent on voting to repeal abortion laws.

While the majority of European Union countries allow early abortions without requiring a reason, Malta, Ireland, Northern Ireland and Poland stand apart for either banning the procedure completely or having strong restrictions in place.

The long fought-for referendum will give Irish people a chance to vote on removing a constitutional provision which bans abortion in all circumstances other than where there is a risk to the life of the pregnant woman.

Katherine Zappone, the Minister for Children and Youth Affairs, said she is confident new abortion legislation can be approved by parliament and put in place before the end of the year.

The magnitude of the predicted victory exceeded the expectations of abortion rights activists.

They have suggested in recent days that if the referendum is defeated, the constitution could instead be amended again to allow for abortions in "hard" cases such as rape, incest and fatal fetal abnormality. Exit polls indicated that the repeal was endorsed in urban and rural areas alike, with strong support from both men and women.

Another woman shared that she had travelled from Queensland, Australia, to Dublin in order to vote.

A Sky News survey conducted this month found 47 per cent of voters were in support of the reform and 37 per cent were against, while an Ipsos poll commissioned by The Irish Times found 44 per cent were in favour of change and 32 per cent were against.

Not everyone could contain their emotions.
