Carns, nick-named ‘Action Man’ because of his military background, has already hinted at his leadership ambitions. Could he now potentially join the likes of Andy Burnham and Wes Streeting in challenging Sir Keir Starmer?

Sky’s Mhari Aurora is joined by political correspondent Amanda Akass to discuss Carn’s career, and how likely a contender he is for the country’s top job.
