'And pick up your smoking gun on the way out." It was quite simply the killer interjection; one containing just the right amount of sarcasm to really get under the skin of its target. Or - more accurately in this case - loser.
You do not usually associate that word with Winston Peters. But his promise to dish more dirt - sorry, fresh information - on Judith Collins, such that she would be "gone by Monday", was a dismal failure in Parliament yesterday.
It must have been especially galling for Peters that the paralysing interjection came from his one-time New Zealand First colleague, Tau Henare. The pair fell out when the National-New Zealand First coalition government fell apart in 1998.
A "smoking gun" is proof that something which was thought to have happened, actually happened.
