There's growing speculation Chris Luxon is at risk of being rolled ahead of the election, with Chris Bishop being touted as a potential replacement. 

An opinion piece by Audrey Young was released today, and it claimed that Labour was going extra hard on Bishop over the cycleway project because he was likely to take over the party by 2026.

Newstalk ZB senior political correspondent Barry Soper says National's taking a hit in the polls and there's discussions about Luxon's leadership abilities taking place.
