Almost £100,000 paid by the consultant, Mr Frank Dunlop, to councillors in the 1990s is still unaccounted for, despite the completion of the Fianna Fail and Fine Gael inquiries into payments to politicians.
Both reports account for only £85,000 - less than half of the £185,000 which, Mr Dunlop told the Flood tribunal, he gave to members of Dublin County Council in the last decade.
The Fianna Fail Standards in Public Life Committee report, published on Wednesday, showed that 11 of the 45 councillors or former councillors interviewed were paid a total of £76,000 by Mr Dunlop. These sums ranged from an amount of between £50,000 and £52,000 paid to Mr Liam Lawlor, down to a total of £500 paid to Mr Sean Ardagh TD.
The Fine Gael report found that Mr Dunlop paid a total of £8,000 to six party members. The highest amount was a total of £3,500 paid to Senator Liam Cosgrave, while Cllr Anne Devitt received £400 towards an election leaflet.
The amounts which the Fianna Fail and Fine Gael inquiry teams were told about fell £85,000£100,000 short of the total of £185,000 which, Mr Dunlop said in evidence to the Flood tribunal, he paid to politicians since 1991.
Mr Dunlop's evidence showed that 16 payments totalling £112,000 were paid in 1991. A further 14 payments totalling nearly £50,000 were paid in 1992. The balance of eight payments made since 1993 totalled £23,000.
Sources in both parties conceded yesterday that there are still huge gaps in the payments which Mr Dunlop said he made. However, they pointed out that some of this money could be amounts that were paid to councillors who have died or to figures not interviewed by the inquiries.
There are still some significant amounts of money, which Mr Dunlop told the tribunal he paid to councillors, which have not been explained.
