Supporters of gay marriage in Ireland are hoping the move to legislate for gay marriage in the UK will influence the Irish Government.
The topic of same-sex marriage is to be discussed at a meeting of the Constitutional Convention here in April.
The group Marriage Equality has said its members are confident the outcome of the discussions will be positive.
As it stands, same-sex marriages are banned in Ireland. The Civil Partnership Act only provides for limited tax and inheritance rights.
Grainne Healy (pictured) of Marriage Equality said she hoped the Government would follow up on the recommendations made by the constitution.
“We would be confident that the (Constitutional) Convention will be able to bring forward a recommendation for the provision of marriage equality in Ireland,” she said.
“Our concern would be that the Government will then take it up…With Eamon Gilmore in government, we would hope they would be able to push for a resolution to this issue, whether it be a referendum or a legislative resolution.”
