With less than a month to go until the marriage referendum, 72% of voters say they'll vote 'yes', while 20% have said they're voting 'no'.
That's according to the latest Red C Poll for the Sunday Business Post.
The poll was conducted between Monday and Wednesday last week among 1,006 adults. They were also questioned about the Government, and results show Labour and Fine Gael have taken a hit in the popularity stakes.
Both parties are now down by two points - to 25% and 8% respectively.
Sinn Fein have risen five points.
