In a week that was set to be dominated politically by Labour's continued handling of the Covid-19 outbreak, one email from former National Party leader Judith Collins shook up the country's political landscape.
In an emergency episode of On the Tiles, the Herald's politics podcast, senior political journalist Thomas Coughlan is joined by Newstalk ZB's chief political reporter Jason Walls to dissect the implosion of the National Party's leadership.
Collins stunned press gallery journalists and the public on Wednesday night when she released a press release saying Simon Bridges - who was rumoured to be considering a coup against Collins - had been demoted and stripped of his portfolios over historic allegations of harassment and inappropriate comments made to a female colleague.
The move backfired against Collins, with a caucus meeting on Thursday seeing her MPs voted her out as leader - replacing her with Dr Shane Reti as an interim leader before a formal decision is made next week.
