Green Party co-leader Metiria Turei has shot back at departing Labour MP Shane Jones, saying his personal attacks show he does not have control over his emotions.
Mr Jones took a parting shot at the Greens after announcing his resignation, saying that he could never have worked under Greens co-leader Russel Norman in a coalition arrangement.
Ms Turei said this morning that she thought the Labour MP would have left Parliament "with a bit more dignity''.
"I was kinda nice about him yesterday - I regret that now,'' she told RadioLive.
"I know he's a colourful guy and he has colourful language, but just continually insulting people is a really bad way to leave your work environment. He's not going to be missed, I think.''
