Former Green MP on Darleen Tana scandal

A former Green MP said unless Darleen Tana resigns as an MP - the Party could be embroiled in the saga dragging on for the rest of the parliamentary term. Darleen Tana has quit the party following the release of a report on allegations of migrant exploitation at her husband's business, but remains an MP. She's rejecting the report's findings, and hasn't said whether she'll stay in parliament. Former Green MP and political commentator Gareth Hughes spoke with Ingrid Hipkiss.
