A former senior executive at NAMA has alleged widespread breaches of the law within the agency on the issue of confidentiality and commercially sensitive information worth millions.
Enda Farrell claims multiple high-level briefings and leaking of information from within NAMA to third parties, according to Newstalk radio.
In documents, the former senior executive gives his account of his time at NAMA.
Enda Farrell claims outside parties with interests in property were informed of property price, land value or rent rate information held within NAMA.
The head of the Public Accounts Committee said an independent inquiry into the leaking of information from NAMA is likely to be needed, even after its top officials appear before the Committee this morning.
TDs on that committee have said it is an opportunity for NAMA to address information put into the public sphere by parties who have an interest in damaging NAMA's reputation.
The former senior executive at NAMA is himself the subject of a Garda investigation for his actions.
His allegations have also been made to Gardaí and a decision on prosecuting him is outstanding from the DPP.
