The story that has made the front page of the Herald this morning and dominated the conversation was the leadership of Prime Minister Christopher Luxon. He is facing what party insiders describe as “the most difficult fortnight of his leadership”, with growing speculation about his support within National's caucus as Parliament returns next week. Sources say that the whip, Stuart Smith, tried to present Christopher Luxon with evidence that caucus backing for his leadership had weakened. He tried to do that before Easter, but Christopher Luxon did not want to hear this. They did not have the meeting. It's understood those who believe Luxon should step aside might act in the next two weeks, although a formal leadership challenge or confidence vote is still seen as unlikely. Instead, the preferred option amongst critics appears to be having a good old chat with Christopher Luxon with evidence of his diminished support within his caucus, and that might prompt him to resign or step aside and bring about a change of leader. Now, if that doesn't happen, a challenge could follow, but there's no declared challenger at this stage.  

All of this is at a critical time. Parliament's back for a short sitting block before recessing again ahead of the Budget. Here comes the Budget. Political analysts say removing a Prime Minister during the Budget period risks destabilising the Government. So it's this next fortnight or not, because after that we're into Budget time and that would be even worse for National. 

National Minister Chris Bishop, who has been widely rumoured as a potential contender, was on the radio with Mike Hosking this morning. He came on to talk about the changes to the Warrants of Fitness, but instead he got a little surprise of talk of a coup. Chris Bishop described the situation as “untidy and unhelpful”. He said there's no leadership challenge underway, and he said he will not be the National leader before the election. But the general consensus to that interview was that he was being a little shifty, and he knows a lot more than he was letting on. How could he not know the feeling in the caucus? He's around there the whole time. How could he not know that three guys had actually come to Thomas Coughlan? But he claimed he didn't. 

Furthermore, can I just remind you that Chris Bishop is scheduled for an interview with Jack Tame on Q&A on Sunday, so you know this issue is going to continue bubbling away. Behind the scenes, tensions were already evident before Parliament recessed. We reported, everybody reported, that Christopher Luxon faced pressure from within caucus during the final sitting week and he ended up reshuffling the party, hopefully to stabilise it, but look at this, it's still rumbling on. When party whip Stuart Smith got ghosted by Christopher Luxon, he ended up raising all his concerns with deputy leader Nicola Willis instead. We've got a poll out right now and those numbers are adding to the pressure. National is currently sitting well below Labour and another major poll is due next week. So, all eyes are now on the coming days and how Christopher Luxon and his senior colleagues respond.
