United Future leader Peter Dunne says a private prosecution being brought against him by a former accountant is "nonsense".
Wellington man Graham McCready filed papers today at the Wellington District Court and sent documents to Mr Dunne.
Mr Dunne said he received the documents today, but had not had a chance to get a legal opinion on them.
He said his initial reaction was that the charges were "simply nonsense".
Mr Dunne is the third politician Mr McCready has targeted for prosecution, alongside ACT leader John Banks and Labour MP Trevor Mallard.
