Are the Greens a progressive party? Are they enemies of the labour movement that need combatting alongside the Tories, UKIP, LibDems and the rest? I ask because, as Graun readers may have seen, Ian Sinclair posed the question last week; "why does the left ignore the Green Party?" It's a fair enough question to ask. Ian provided a list of policies most Labour types wish we would take on board. Wild ultra-leftist promises like renationalising rail and public utilities, which also happen to be backed by the public at large. All progressive, all would go some way to making Britain a better place to be. Yet the reasons why the left and the labour movement don't treat the Greens favourably is only partly thanks to the enduring image of sandal-wearing, lentil-snorting hippy-types. The main reason, which is occasionally articulated by the far left, is that the Greens are anti-modernist and mainly based on an "alien" class force - the petit bourgeoisie. Or so we're told. Is that really the case? Are the Greens an organisation the left should shun, despite their demonstrably centre-left political programme?
