A SECRET donor has offered €500,000 to help to fund Sean Quinn's legal action against the former Anglo Irish Bank, the family has claimed.
The Quinns are now representing themselves in a host of legal actions against the IBRC (formerly Anglo) after parting ways with their legal team.
The family say there have been "multiple offers of assistance" and said they were "exploring all options".
The Quinns are suing the bank for alleged fraud, claiming more than €2bn worth of loans given to them by the bank were unlawful because they were used to prop up Anglo's collapsing share price.
The family's bank accounts have been frozen by the courts and receivers have been appointed over their assets -- leaving them with no control over their financial affairs or access to millions the bank believes they have stashed away.
The Quinns, who are allowed to apply to the courts to release money for legal representation, have denied they are sitting on a "pot of gold".
In a statement the family said they were "absolutely determined" to proceed to trial with the main case against Anglo.
The identity of the alleged €500,000 donor is not known, but their existence was revealed at a recent committee meeting of Concerned Irish Citizens (CIC), a lobby group formed to support the family.
The group, which met last night to finalise plans for a rally on Sunday in Ballyconnell, has claimed that the group has been inundated with offers of cash.
"A lot of people have come forward to offer their financial support," said CIC's Patricia Gilheany. "They feel very strongly about the case."
Today, the names of speakers from the business and community world who will address the rally were due to be revealed.
Several members of the Quinn family are also expected to speak at the event.
The family's woes deepened yesterday when Paul Appleby, the outgoing Director of Corporate Enforcement, said the administrators of Quinn Insurance Limited (QIL) could go to the High Court to make former directors of the firm personally responsible for the company's debts.
