Labour Party deputy leader Annette King is not retreating from calling John Key a scumbag, and rejects his explanation for his provocative reaction to a protester who tried to throw himself into the debating chamber.
On Wednesday a 54-year-old man tried to hurl himself from the first-floor public gallery into the debating chamber, but was prevented by security guard Dennis Laplanche and others.
The incident startled MPs, and Mr Key said Labour should be ashamed.
He made a gesture which Labour MPs say was a throat-slitting action.
Ms King and Trevor Mallard shouted "scumbag" at him, and leader Phil Goff said it was a "disgrace" that he'd tried to blame Labour. Mr Key rolled his eyes and left soon after.
