LISTEN ABOVE AS BARRY SOPER SPEAKS TO TIM BEVERIDGE

Jami-Lee Ross' days in the National Party caucus look numbered.

In a series of tweets, Ross claims Bridges pushed him out on medical leave after confronting him with a recording of Bridges discussing unlawful activity.

Newstalk ZB political editor Barry Soper told Tim Beveridge  the future for both Bridges and Ross is looking messy.

"This is a direct challenge to Simon Bridges' leadership, he has got to go in and ask for the expulsion of Jamie Lee Ross from the National Party caucus tomorrow when they have their meeting."
