Businessman John Kennedy has told the Mahon Tribunal that he gave incorrect information about a dinner donation to Bertie Ahern.
In an amended statement sent to the tribunal this morning Mr Kennedy now says he does not know how much money was collected and that he did not organise the event in 1994.
He also now says the donation was not a political contribution but made because of Mr Ahern's financial difficulties.
Mr Kennedy said he told it was a terrible thing that Mr Ahern was the Minister for Finance in Ireland and did not have a bob in his pocket.
He says another Manchester businessman Tim Kilroe told him that there would be a whip around for him and to bring a few bob.
Mr Kennedy told Henry Murphy SC for the tribunal that he did not say this in his first reply to the tribunal in July 2006 where he said the donation was to support Mr Ahern in changing the face of Irish politics.
Mr Kennedy said he did not want to embarrass Mr Ahern by saying the money was given because of difficulties arising from marital separation.
He also now says that he did not give his £1000 donation directly to Mr Ahern on the night, but gave it to Mr Kilroe he also changed his evidence on two other points.
In July 2006 he said the dinner was organised by himself, the late Mr Kilroe and others.
This morning in his amended statement through his solicitor he said it was actually organised by Mr Kilroe
And in his original reply he said they raised some £10,000 for Mr Ahern
Now he says he does not know how much money was collected
Mr Kennedy said he had organised charity events with the late Mr Kilroe among the Manchester Irish community, but he said the businessmen present for Mr Ahern's donation were Mr Kilroe's friends not his.
He only knew three of the businessmen who he named but who are now deceased.
Mr Kennedy said Mr Ahern had not offered to pay back his donation of £1,000
Former lobbyist Frank Dunlop has denied at the Mahon Tribunal that he falsified his diaries to protect Cork businessman Owen O'Callaghan.
Frank Dunlop has previously testified that developer Owen O'Callaghan was not aware of bribes paid to politicians in relation to his Quarryvale development.
Mr Dunlop was asked today about obliterations and alterations that he made in his diaries before handing them over to the inquiry in 2000.
Forensic analysis commissioned by the inquiry shows that one entry in November 1993 was partly rewritten and partly scribbled over to remove a reference to paying the late Liam Lawlor £1,500.
This entry is alongside a meeting with Owen O'Callaghan.
Another entry in June 1992 records a meeting with OOC, another entry L has been changed to F.
Mr Dunlop admitted that other references and payments to Mr Lawlor were contained in diaries given to the tribunal.
But he denied falsifying the entries that would associate Mr O'Callaghan with a payment to Mr Lawlor.
Mr Dunlop said he could not say why he did it.
