Transport Minister Seamus Brennan has said there will be no turning back from proposals to break up Aer Rianta.
Over the weekend there had been reports of a split in the Cabinet over the proposals involving Finance Minister Charlie McCreevy.
However, speaking on Morning Ireland, Mr Brennan said he hoped to resolve what he termed 'financial issues' with the Department of Finance in the not too distant future.
Tanaiste Mary Harney has also dismissed suggestions of a row over the proposals to break up Aer Rianta.
Asked on the Week in Politics programme about the delay in publishing the Bill to allow for the break-up, Ms Harney said there were technical issues and technical challenges involved but said she would see the Bill 'before the summer'.
Labour Leader Pat Rabbitte had claimed the Department of Finance were 'appalled' because the proposal would end up costing the taxpayer a lot of money and was breaking up a successful company.
