Taoiseach Bertie Ahern has rejected reports that there was a written agreement with the Green Party that he would resign if the Mahon tribunal report made negative findings against him.
He told Fine Gael leader Enda Kenny that there was no written agreement, that the allegation he had been asked to answer in the tribunal was that he had received money from developer Owen O'Callaghan.
Mr Ahern said he would be cleared on all those issues "because I received nothing from Owen O'Callaghan in any matter".
Mr Kenny also questioned the Taoiseach about comments he had made in the Dáil in 1997 about the need for the highest political standards and asked why the standards Mr Ahern applied to Mr Haughey did not apply to himself.
Rejecting the allegation, Mr Ahern said "I received money from two different sets of very close friends and paid back that money in full and the interest".
He added: "I dealt with it fully and completely and in a proper fashion and I do not think I have in any way contravened anything that I said in this House."
Mr Kenny returned again to the issue of personal payments to the Taoiseach and said there had been a reference in the Irish Daily Mail to a "written agreement made by you with the negotiating team for the Greens that you would resign if the tribunal found that you took bribes, which I don't make a claim against you; if it found that you did not co-operate with it or if it found that your evidence was unreliable".
He called on Mr Ahern to confirm the agreement, but the Taoiseach said that "Deputy Kenny knows well there's no written agreement" and the Green party had said it would "await the findings of the full tribunal".
He added: "The allegation I have been asked to answer is that I received money from Owen O'Callaghan." He said he would be cleared in all those issues "because I received nothing from Owen O'Callaghan in any matter".
The Taoiseach reiterated that "I received money from two different sets of very close friends and paid back that money in full and the interest".
He said: "Deputy Kenny, I know one of your spin doctors keeps saying its €300,000. It's £48,000 and I paid back just short of £99,000."
The Fine Gael leader quoted comments by Mr Ahern in 1997 about payments to Mr Haughey that "the public is entitled to have an absolute guarantee of the financial probity and integrity of their elected representatives, officials and above all ministers".
Mr Kenny said: "That's the problem that I have with you as Taoiseach, that you do not apply the standards that you apply to others to yourself. If it was wrong of Charles Haughey to receive money it was also wrong of you to receive money."
Mr Ahern said he did not want to get into either what the late Mr Haughey or anyone else did. "It's drawing in people that are in the grave and other people that are not in the grave."
The Taoiseach said he was "a huge supporter in this House of bringing in rules and standards", he had given a full account of what he had received, and did not believe he had in any way contravened what he had said previously in the Dáil.
