Chris Luxon says he didn't lobby for his party deputy, Nicola Willis, to be Deputy Prime Minister.

Willis today said she wasn't in the race and Winston Peters or David Seymour are likely to get the job.

ZB political editor Jason Walls says it's looking likely that Winston's the new favourite to take up the role as Deputy Prime Minister.
