Fine Gael has called for an interim report to be published on the investigation into Anglo Irish Bank.
It has also asked the Minister for Justice to state when the garda file on the investigation is going to be sent to the Director of Public Prosecutions.
In a statement, Finance Spokesperson Michael Noonan pointed out that nobody has yet been prosecuted in Ireland over irregularities in the banking system.
Mr Noonan said this was in contrast to the US, were almost 50 prosecutions have so far been secured.
He expressed concern that the slow pace of progress may be due to a lack of political will within Government.
Minister for Justice Dermot Ahern has described Mr Noonan's statement as 'alarming'.
Mr Ahern said that Ministers for Justice have no role in garda investigations, prosecutions or the sending of files to the DPP.
He said any person guilty of fraud or financial misconduct would be brought to justice as soon as possible.
However, he said that political interference in policing or the independent prosecution system could not be permitted.
