A senior National MP's throwing cold water on the idea the Prime Minister will be voted out of his job as National party leader today.  

Mark Mitchell says there's been a lot of speculation from media commentators about what will happen, but there's no confirmation.  

He told Mike Hosking everyone's getting ahead of themselves. 

Mitchell says he sat with Luxon until late last night to make sure he's in the "strongest possible position today and supported for the caucus meeting". 

He said he'd seen media reports claiming Chris Penk had been hitting the phones to shore up support for Erica Stanford, but stressed there would be no discussions until the 9.30am meeting. 

Affirming his loyalty to Luxon as leader, Mitchell described himself as "very old-fashioned" and said he took "great offence" to people who work outside that operandus. 

"If you've got someone that's not been loyal to the leader inside the caucus, you can't do it publicly. You actually front up and sit down and say, 'These are what the issues are'," he said.
