Labour leader Andrew Little says he was justified in telling Napier MP Stuart Nash not to speak at a Wellington mayoral forum because the candidate, a former Labour Party member and Porirua mayor Nick Leggett, was a right-wing competitor to the Labour-endorsed candidate.
"It was an event involving a number of right-wingers who have routinely sought to undermine the Labour Party," Little told reporters today.
"It is not right for a Labour MP to be sharing a platform with people who do that.
"We are a political party, not a debating society."
Asked about calling Leggett a right-winger, Little said his campaign manager was a well-known Act Party identity.
