Simon Bridges better watch his back - and his front - because Judith Collins isn't ruling out another shot at the National Party leadership.
Ms Collins lost the recent five-way battle to Mr Bridges, who took over from Bill English.
During the short campaign she infamously tweeted she prefers to stab "from the front", after a caller to her Papakura electorate office told her to "stop backstabbing Jacinda".
Ms Collins appeared on The AM Show on Friday, and was asked if she could definitively rule out rolling Mr Bridges if he failed to win over the public.
"Oh, you know me," she replied, not ruling it out - with a laugh.
"For now," added Labour MP Phil Twyford, suggesting she might give it a go when "Simon Bridges goes below 35 percent in the polls".
Ms Collins quickly hit back: "You guys are always around that anyway."

- Simon Bridges lets slip who might be in for a promotion
So far, the only promotion Mr Bridges has announced for his shadow Cabinet is Amy Adams, who'll take over the key role of finance. Ms Collins is yet to find out her new portfolios.
"The good news is you haven't gotten the arse, because you would have known that by now, wouldn't ya?" asked AM Show co-host Mark Richardson.
"No, I definitely don't have the arse," Ms Collins responded.
Paula Bennett is staying deputy leader.
