A new opinion poll shows that over three-quarters of people support same-sex marriage.

It is the same level as a previous survey in November.

The RED C poll conducted for RTE PrimeTime and the Sunday Business Post shows that if a referendum was held tomorrow, 76% of adults would support same-sex marriage rights, 19% are against and 5% say they do not know.

80% of respondents think people in same-sex relationships should have the same rights as traditional families.

Almost half - 49% - believe in equal rights for gay people, but say they have some reservations about same-sex marriage.

When it comes to the issue of adoption by gay couples, the poll found 59% have no reservations about it.

And 41% believe people who oppose same-sex marriage rights are homophobic. The poll was conducted on over 1,000 adults between Monday and Wednesday of this week.

Jerry Buttimer is chairman of Fine Gael's LGBT Committee. He told Newstalk Breakfast that those in favour are not taking these results for granted.
