Figures suggest the Republic of Ireland has voted to legalise same-sex marriage in a historic referendum
Government ministers have said they believe it will pass, while prominent "no" campaigners have conceded defeat.
Counting started at 09:00 BST on Saturday morning. An "unusually high" turnout has been reported.
A final result is expected late afternoon on Saturday.
If the change is approved, the Republic of Ireland would become the first country to legalise same-sex marriage through a popular vote.
