If the Greens party room expels New South Wales Senator Lee Rhiannon over their internal disagreements about the Gonski 2.0 legislation, it would set in motion events unprecedented in the history of the Greens.

Reports suggest that the nine other federal Greens politicians are actively considering removing her from the party room with meetings to be held this week over Rhiannon authorising anti-Gonski 2.0 leaflets distributed in New South Wales while the party was in negotiations with the government over the education funding legislation.
