The head of the Dublin Citizens' Assembly has said he believes the city needs a directly-elected mayor for accountability.
The assembly will meet for the final time on Saturday in Dublin Castle to vote on the issue.
The group, which has been meeting for six months, has received contributions from academics, political scientists, former politicians and Lord Mayors of other cities around the world.
The 80 members will also discuss what local government structures best suit the city.
Jim Gavin has been chairing the assembly and told Newstalk Breakfast the capital needs a 'champion'.
"We have a Minister of Rural Affairs, which I think is right, and I think we should have a Minister of Rural Affairs.
"We don't have a Minister of Dublin Affairs, I don't think we need a Minister of Dublin Affairs.
"We certainly need a champion, we need a single source of accountability - somebody that we can say 'The buck stops with me'.
"I grew up in Clondalkin very close to Ballyfermot, I looked at those horrific scenes [and] I struggle to see who's accountable.
"We need somebody who [is] a single source of accountability, they're a champion for Dublin, they're an ambassador for Dublin.
"We need a directly-elected mayor that has executive powers.
"A directly-elected mayor will have a mandate: 'I will execute, for example the Metro' - that's just as a big example."
He said the assembly will be examining what the office might look like.
"What you're voting for on this weekend is what that term of office might be - is it two years, is it three, is it five, is it 10?
"Who's eligible - is it 18, for like a councillor, or is it 21 like a TD?"
He added: "We haven't been asked is it a good or bad idea, we've been simply asked what type of directly-elected mayor should Dublin have.
"Now we have to come together and the members need to vote on those deliberations that they've had and decide on a range of topics.
"I do have a view, I have a personal view, and if there's a split vote I will have to vote... I've the casting vote".
