It's just another sign of how unstable this Green-Labor coalition is.

However it raises other questions. Specifically, how many times have Nick McKim and Cassy O'Connor walked out of Cabinet? What were the issues?

Have the Greens walked out of Cabinet over any decisions related to the upcoming budget?

Did they support the proposal to link politician's pay to Band 9 of the State Service in Cabinet yesterday?

The Greens have long called for greater Government transparency. Well, now is the Greens' chance to walk the walk, as well as talk the talk.

It's time for some honest answers from the Premier and Mr McKim.
