A member of the Stop Out-of-Control Drinking group has accepted that the body's funding by drinks giant Diageo has created a "credibility gap" for the campaign.
Gavin Duffy said he believed the drinks group would not be involved in the campaign in the coming years.
The entrepreneur and 'Dragons' Den' panellist said he believed the group was correct to take funding from Diageo, whose brands include Guinness, but said he respected people's right to question it.
"For me, I think if we can get the funding to start the campaign and start the debate like this to go forward, that is important. I don't see Diageo involved in this into the distant future," he said.
Mr Duffy said the issue was raised by people at meetings, but insisted the group itself was often first to address the matter.
"It has created a credibility gap which is a problem but only a minor problem when you see the number of sign-ups.
