For years Russell Brand has been one of Britain’s most popular comedians, but over the past 12 months he has also emerged as a leading voice of Britain’s political left. He has taken part in anti-austerity protests, spoken at Occupy Wall Street protests and marched with the hacker collective Anonymous. A recovering addict himself, Brand has also become a leading critic of Britain’s drug laws. He has just come out with a new book expanding on his critique of the political system. It is simply titled “Revolution.”
