WHISTLEBLOWER Gerry Ryan has made fresh allegations about the tax affairs of a number of former senior politicians, independent.ie understands.
The allegations have been made in correspondence with the Public Accounts Committee (PAC) and relate to the so-called Ansbacher accounts.
But members of the PAC have been precluded from accessing the correspondence from Mr Ryan following legal advice from Oireachtas lawyers.
PAC members were told this evening that they will be allowed to view the documentation under the supervision of the Parliamentary Legal Advisor tomorrow.
Privately, some PAC members are unhappy that they have been precluded from seeing correspondence sent to them as committee members.
His dossier, sent to the PAC, alleges that that a number of individuals in Fianna Fáil and Fine Gael committed tax evasion and that this was subsequently covered up.
Mr Ryan was appointed by Ms Harney in 1998 to investigate the use of a series of off-shore bank accounts which formed the basis of the Ansbacher affair.
Mr Ryan claims to have evidence that former politicians were named in a "Cayman ledger" in Guinness and Mahon Bank.
All politicians named categorically denied having Ansbacher accounts.
Several authoritative bodies, including the Revenue Commissioners, said Mr Ryan's claims have been fully investigated and that there is no need for further inquiry.
It's believed his latest correspondence with PAC makes fresh allegations and responds to evidence given by Revenue at a recent PAC meeting.
