Fianna Fáil leader Micheál Martin has asked the Taoiseach to agree to establish a commission of investigation into the sale of the property loan book in Northern Ireland by the National Asset Management Agency.
Speaking during Leaders' Questions in the Dáil, Mr Martin said the policy drive was to accelerate the sale of all of NAMA's loan books.
He said it has now emerged that Minister for Finance Michael Noonan knew from March 2014 that NAMA advisor Frank Cushnahan was to be paid a sum from the sale of the loan book to PIMCO.
Enda Kenny said that a commission of investigation would have no jurisdiction in the south in relation to Northern Ireland.
He said the Comptroller & Auditor General and the Public Accounts Committee are the accountable offices for NAMA.
Mr Kenny said the matter is being investigated by the Northern Finance Committee and the Northern Ireland Law Society was now investigating allegations of corruption.
He said the fact is there are no claims of wrong doing against NAMA and the portfolio was closed following an open process to the highest bidder for what it was worth.
Mr Martin said there was a dramatic contrast between how the Taoiseach and Government and the UK authorities were approaching the deal.
Sinn Féin Deputy leader Mary Lou McDonald said the oversight of NAMA is invested in the Oireachtas and the Government.
She said PIMCO contradicted the account given by NAMA chairman Frank Daly that it was asked to withdraw from the sale process and that the agency contests it withdrew voluntarily.
She said facts were also emerging that the same law firms were acting for bidders and sellers at the same time.
She said she believed that the reputation of NAMA was now on the line and she asked how anyone could have confidence in the agency which is why a commission of investigation was necessary.
Public Accounts Committee chairman John McGuinness has appealed to Mr Martin and Ms McDonald to stand back and allow the committee to proceed with its investigation into the sale of NAMA's NI property portfolio.
Deputy McGuinness said the PAC is in the process of sending the transcripts of what NAMA officials said in the committee last Thursday to the various parties involved and is awaiting a response from them.
He also said the committee was in the process of inviting the various parties to appear before it.
The PAC cannot compel those based in Northern Ireland to appear before it.
However, Mr McGuinness said the UK National Crime agency and the Stormont finance committee were looking at the deal.
He also said that the Comptroller and Auditor General had begun an investigation due to the losses involved.
