On social media Shaw has been praised for bringing legitimacy to the Greens, otherwise seen by many as a radical left wing set up.
There are calls for Shaw to set up a new party.
On X (formerly Twitter) contributor hopes that Shaw sets up a “real” environment party that can work on both sides of the house.
“I am sure many would back that. The radical left masquerading as a green party needs to be a thing of the past.”
“James Shaw could go and set up an actual Green Party in time for the next election. I think a lot of legitimate Green issues need to be addressed and the current party is clearly not capable, or focused at all, on doing that,” wrote another.
