The Taoiseach has said allegations about tax evasion by senior politicians will be fully examined by the Public Accounts Committee.
Earlier today, a member of the PAC confirmed to RTÉ that a dossier alleging tax evasion by some politicians over a number of years had been given to the committee.
Speaking in Westport, Co Mayo tonight, Enda Kenny said the matter had come to light as a result of new whistleblower legislation introduced by the Government.
He said he had not seen the dossier in question, but that he understood the issues referred to from the public servant have been the subject of discussion among gardaí and the Moriarty Tribunal.
He said the PAC was taking legal advice and that the matter would be discussed in quite considerable detail.
Mr Kenny said he noted a garda statement this evening that the matters had been investigated in the past and that a file had been sent to the DPP at the time.
When asked if he was aware of any minister in the Cabinet having knowledge of the matter before today's reports, Mr Kenny said he understood there was "a delay in the issue of some documentation because of the retirement of a public servant and because of pressure of work" but this was not an issue that caused him any concern.
Gardaí earlier tonight confirmed they investigated serious allegations sent to them by a serving civil servant a number of years ago.
The allegations were received in 2007 and gardaí say they were fully investigated.
The investigation was conducted by the Garda Bureau of Fraud Investigation and RTÉ News understands that the complainant was interviewed by detectives.
A file was sent to the Director of Public Prosecutions.
Yesterday, members of the PAC received a letter and a dossier of allegations of substantial tax evasion by people, including senior politicians and at least one former judge, going back over 15 years.
The allegations were made by a serving civil servant who sent the dossier under the new Protected Disclosure legislation.
He uncovered the alleged tax evasion in the course of his official duties.
The civil servant also makes serious allegations that senior ministers and a number of State agencies failed to fully investigate his findings.
The Garda Press Office said this evening if any new or further information on these matters is provided they will be fully investigated.
Tax evasion 'not acceptable'
Minister for Health Leo Varadkar has said that tax evasion by anyone is not acceptable and there can be no tolerance of it.
He said he himself is tax compliant and he felt sure the PAC will investigate further.
Mr Varadkar also said there is now legislation in place to protect whistleblowers.
PAC Chairman John McGuinness said he believes this is the first disclosure to the PAC under the new legislation, and as such, it is taking a cautious approach and taking legal advice.
That legal advice will be discussed next Thursday.
Asked whether he had any knowledge of the matter this morning, Minister for Public Expenditure and Reform Brendan Howlin said he knew nothing about it, apart from what he read in the paper.
Speaking following a meeting of EU finance ministers in Brussels, Minister for Finance Michael Noonan said he only knew what he had read in newspapers, but said that was a matter for the committee, after scrutinising the submission, as to whether it should refer the matter to "the Garda Commissioner, to the Revenue Commissioners or both…"
The committee, he said, had a role under whistleblower legislation.
The Revenue Commissioners have said they will not be commenting.
Former politician denies allegation
One of the former politicians alleged to have engaged in tax evasion through offshore accounts has told RTÉ News he denies the allegation.
The former politician confirmed that he had had an account at the financial institution that was under investigation, but said it was a domestic, not an offshore account.
He also voiced concern that such allegations were being made about him by someone whose name he had not been given.
