The Greens continue to call for Darleen Tana to leave Parliament - after she broke her silence last night

Tana left the party, after it received a not-yet publicly released report into her knowledge of alleged migrant exploitation at her husband's business.

She's told One News she did not exploit migrants - and claims she's been up-front with her party and the inquiry.

But co-leader Chloe Swarbrick says the investigation wouldn't have been needed, if Tana had been honest with them.

She says the report lays bare a betrayal of the behaviour expected of an MP - and it's in everyone's best interest Tana takes responsibility.
