MAVERICK politician Mick Wallace says he plans to make further allegations in the Dáil about the controversial sale of Nama's property loan portfolio in Northern Ireland.
The independent TD rocked Stormont in July after he claimed a £7m offshore fund linked to the Nama deal was earmarked for a northern politician or party.
His explosive claims under Dail parliamentary privilege have sparked a criminal investigation and inquiries on both sides of the border.
Meanwhile, it has emerged that DUP leader Peter Robinson has threatened to sue Mr Wallace over allegedly defamatory comments posted on Twitter.
Last night Mr Wallace said he would not be deterred by the threat.
The Wexford TD also revealed he plans to make further claims in the Dáil chamber about the northern loan book deal, known as Project Eagle, within the next fortnight.
"With regard to Project Eagle we have plenty to say on it and I do intend to have my say on the issue when the first opportunity avails," he said.
"In the next fortnight I expect to speak on the issue.
"We have a lot of information but obviously I have to be careful how I use it. We're working on stuff at the moment, but how much I can say I just don't know yet."
Nama (National Asset Management Agency) is the 'bad bank' set up in the Republic to clear property loans from bailed out lenders.
Its northern loan portfolio was purchased in April last year by US firm Cerberus for £1.3bn – the biggest ever property deal in Northern Ireland.
Nama and all private firms involved in the Northern Ireland assets sale have denied wrongdoing.
Mr Robinson – who has temporarily stood aside as First Minister amid a political row over the murder of an ex-IRA man – has also emphatically denied any link and said no-one in his family or the DUP hoped to benefit "one penny" from the huge property deal.
In response to the legal threat Mr Wallace said: "One would have thought that Mr Robinson would make better use of his time if he concentrated on trying to stabilise the political situation in Northern Ireland, rather than taking legal action to shut down debate on an issue that is of great public concern, in particular for the taxpayer in the Republic.
"What is needed is open debate and transparency – something in short supply, north and south of Ireland."
Mr Wallace's solicitor Gareth Noble also said: "It is not considered that the commentary referred to on social media was in any way defamatory."
He added: "Deputy Wallace has a proud record of highlighting important matters in the public interest in relation to issues which demand transparency, openness and accountability.
"He shall not be distracted or deterred from continuing this work by the threat of legal action."
Earlier, Mr Robinson confirmed his lawyers had been instructed to pursue the case.
Speaking from Stormont Castle, the DUP leader said it was important to challenge such claims.
"He (Mr Wallace) will not be the last," he said.
His solicitor Paul Tweed, who has represented celebrities such as Britney Spears, Harrison Ford and Louis Walsh, said Mr Wallace had been "put on notice".
The DUP previously threatened to take legal action against a blogger over allegations made about the Nama scandal.
Mr Robinson later indicated he would not take court action against "village idiots" on social media, saying "they don't have any money so you can't sue them".
