The Communications Minister Alex White is confident of a 'Yes' vote in the upcoming marriage equality referendum.
Mr White, who is the Labour Party's Director of Elections, says nobody in this country will be adversely affected if the referendum is passed.
He also believes people will view this as an issue of equal rights and vote accordingly.
He said: "I think the people in Ireland are fair-minded and they will see that this is a question of equality.
"We have a written constitution, that we all respect and believe is at the heart of our democracy and our society, and let's have everybody treated equally under that constitution.
"It's a simple proposition, but a very profound one, and I think the Irish people will get behind it."
