National Party President Peter Goodfellow has mounted an attack on Acting Prime Minister Winston Peters, saying National had "dodged a whisky-swilling, cigarette-smoking, double-breasted and irrational bullet".
Speaking at the National Party conference, Goodfellow said that in hindsight National had a lucky escape in Peters' decision to side with Labour after the election last year and to send National into Opposition.
Senior MP Nick Smith later echoed Goodfellow's sentiments, saying his worst time in politics was when he was around the Cabinet table with Peters in the 1990s.
"Yesterday on the radio I heard the Green Party griping about eating dead rats. My message to them is get used to the taste.
It brought back bad memories. As much as I, like you, have been frustrated about the election outcome, I share the President's view that our party dodged a bullet."
