The campaign group MarriagEquality says its latest survey shows increased public support for gay marriage in Ireland.
Eighty-four per cent of respondents to an opinion poll conducted this month by Lansdowne Market Research said they supported civil marriage or civil partnerships for gay and lesbian couples.
This is the same figure as a similar survey carried out in November 2006.
However, 58% said gay and lesbian couples should be allowed to marry in registry offices, compared to 51% in the previous survey.
Meanwhile, the number who said such couples should only be allowed to form civil partnerships was down from 33% to 26%.
