The Finance Minister Michael Noonan has said he will not rule out a Commission of Investigation into the sale of Nama's Northern Irish loans.
However, he said an inquiry can only be ordered if the Public Accounts Committee investigates the issue first.
Michael Noonan is due to bring a report from the Comptroller & Auditor General to the cabinet tomorrow morning.
The mammoth report is due for release tomorrow after it is cleared by cabinet.
However Mr Noonan said there is nothing in the report to suggest anything "illegal or improper, or any irregularities in the way Nama behaved".
