A bankrupt businessman with convictions for tax avoidance is suing independent MP Brendan Horan and RadioLive in a $650,000 defamation claim.
Colin Henderson is being represented by Brian Henry, who has acted as Winston Peters' lawyer. Mr Henderson has also passed information to the NZ First leader about Mr Horan, a former MP for the party.
The Herald has confirmed that Mr Henderson, 66, has taken a case in the High Court at Auckland against MediaWorks and Mr Horan over comments made by the NZ First-turned-independent MP on Radio-Live.
Mr Henderson is understood to be seeking $300,000 from MediaWorks, which owns the radio station, and $350,000 from Mr Horan.
The case is the latest in a series of allegations following the falling-out between Mr Peters and Mr Horan, who was dumped from NZ First over accusations he had misused money from his mother Olwen's bank account before she died.
