Are you talking about the parliamentary left and right here?

"laissez-faire leftist" are two words otherwise seldom heard together.

If so, I don't think Orwell was discussing Parliamentary left and right divisions, but cultural ones. And so in his case "laissez-faire leftist" wouldn't make much sense.

on edit: oops, sorry, I saw it was your last word. So I guess I will never know what it is you're actually talking about.
