The Taoiseach has rejected the accusation that the Banking Inquiry was "worse than useless"
A member of the banking inquiry has called on Fianna Fáil to apologise for Brian Lenihan's claim that "we all partied".
Sinn Fein's Pearse Doherty says the claim is dismantled by the findings of yesterday's report.
Deputy Doherty was speaking as the Dail debated the findings of the report, which he refused to sign.
He says the report shows how the public hold little responsibility for the banking collapse.
"It was caused by the lending and speculative activities of a tiny group of bankers (and) developers that were spurned on by a Fianna Fail led government that, when the crisis revealed itself, gave them a blanket guarantee that led directly to Ireland seeking a bailout programme," Doherty said.
"Will we hear an apology for the 'we all partied' line? I won't hold my breath," he added.
Earlier today the Taoiseach Enda Kenny rejected claims the Banking Inquiry was "worse than useless".
The description came on Newstalk Breakfast from Professor Bill Black - a professor in economics and law at the University of Missouri in Kansas city, and one of the first witnesses before the inquiry.
The investigation into the banking crisis reached its conclusion, with the publication of the report yesterday.
It took 18 months, €6.5m and 375 pages to figure out who is responsible for a near-decade of austerity.
The European Central Bank (ECB) was blamed for forcing the Irish taxpayer to take on the costs of saving the banks.
Earlier, Prof Black told Newstalk Breakfast we will not learn anything from this report to prevent this crisis happening again.
However, Enda Kenny rejected this description and says he will reflect on if another referendum is necessary to ensure any future inquiry has powers of investigation.
Meanwhile, the Dáil has begun its 90 minute debate into the report's 76 findings.
Beginning the debate, the inquiry chairman Ciaran Lynch hit out at the ECB for refusing to cooperate.
