I keep hearing about militants in the Labour Party that were apparently Trotskyites and the like. I don't know when they first appeared, but here's a challenge to see how much potential they had politically.
What would it take them to succeed? Keep in mind, here, that can mean successfully getting into office or something similar.
Come up with something if that's who is being referred to.
EDIT: I see this started in the 1960s, and continued into the 1980s. Well, find a way for them to grab power in that time, perhaps the economy keeps getting worse?
