Greens in Czech Republic are no radical communists, only radical fascists call them this way.
I know the leader has departed but obviously he had the party's support. He lost support because of bad election result, not because they didn't agree with him. From my discussion with other significant Green party members that want to nationalize infrastructure companies, ban cars, increase taxation a lot, redistribute wealth in large amounts etc I'm not really sure what else should they be if not radical communists.
Please don't call people who aren't actually fascist "radical fascists" ever again. It's a huge insult here; the fascists killed a lot of my family.
Fun fact for others: We call the Green party "The Watermelons" - because they're green on the outside but red on the inside.
Our 'proper' left parties that have some power are those old-school leftist parties that are pro-Russian. The irony is that they are usually quite fond of Trump.
And I sincerely wish our Green Party had ever gotten 3%.
I’m not sure what you consider left but I’d hazard a guess we disagree based on your comment.
Young greens are tightly linked with the Green party. It is in fact the youth wing of the green party.
