I would like to see a broad movement of left-leaning Labour MPs to the Greens. I think the green movement is in the ascendant, due to the climate thing. Cop26 and the others have largely shown us mainstream politicians are ineffectual so if the groundswell of public concern and public opinion is that we need to do stuff, not talk about doing stuff, then the green message must surely resonate? But the greens lack political expertise, which is where an influx of seasoned, left wing politicians could be helpful.
