Michelle Boag, Ben Thomas discuss National leadership

Rumours continue to swirl about a possible challenge to Simon Bridges' leadership by senior MP Judith Collins. The National caucus met yesterday for the first time after a two-week break. Arriving at the meeting National MPs were asked if they're still putting their support behind Mr Bridges. Mr Bridges emerged from the meeting declaring he was comfortable and confident in his leadership of a united caucus - but that hasn't put speculation of a leadership challenge to rest. Michelle Boag is a former National Party president and Ben Thomas is a political commentator. They join Guyon Espiner in the Auckland studio to discuss.
