Luxon calls urgent meeting to resolve speculation

With speculation over his leadership swirling, National's Christopher Luxon is calling all National MPs to the capital for an urgent in-person caucus meeting tomorrow. He's just come off a fortnight defending his comments to Rotorua small businesses, his Foreign Minister telling a Chinese-born MP to go back where he came from, and announcing on live radio he wants a referendum on MMP - without having told his caucus. Political reporter Russell Palmer has the story.
