A senior National Minister believes a disagreement between David Seymour and the Prime Minister is no big deal

Seymour threw back Chris Luxon's words at him, saying HE was "ill advised" to call Seymour ill-advised - for writing to Police to advocate for constituent Philip Polkinghorne - who was later charged with murder, then found not guilty.

Seymour could also be in for a chat with the Speaker - for yesterday trying to drive a Land Rover up Parliament's steps, for charity.

Chris Bishop says people shouldn't get worked up.

He says we live in a robust democracy - and this is politics.
