It will come as no surprise that Brand has endorsed veteran left-wing MP, Jeremy Corbyn.
In Brand's latest 'Trews' video, the 40-year-old looks at who is "worse" for Britain - Corbyn or Tony Blair.

Russell Brand backs Jeremy Corbyn in his latest Trews video
The host of the popular YouTube channel begins the episode listing Corbyn's policies, which include condemnation of the Iraq War, opposing capping benefits, scrapping Trident, challenging sexism, re-nationalising energy and rail companies and bringing in rent controls.
Brand says: "It seems to me that Jeremy Corbyn is being vilified and attacked by the media and by the establishment simply because he is in public talking out on behalf of ordinary people.
"And those policies that we listed at the beginning of this episode, none of them seem absurd to me.
"The other candidates in the Labour leadership election - and I don't really want to be involved in leadership elections or voting-type stuff any more - but they are interchangeable, even though they are different genders, like the Burnham one, the Cooper one.
"I think I have met some of them but they all sort of just float around and seem like they could have podded off of him [points at screen of Tony Blair]. And that's what worries me about it."
Brand later tweeted to his 10.7 million followers that he did not want to be involved in "leadership elections or voting type stuff anymore but..."
Let's hope Brand's endorsement isn't worrying the Labour leadership frontrunner...
The Peep Show actor said: "He's a nice guy, totally marooned in 1980s politics. And I remember the 1980s very well. The Bennites f****d Labour. And then we had 17 years of Tories. Lots of people suffered while the Left kept their splendid principles. F**k that. Come on, guys." (credit:Zak Hussein/PA Archive)

The singer said: "He is one of the only politicians of note that seems to truly recognise the dire inequality that exists in this country today and actually have a problem with it. There is something inherently virtuous about him, and that is a quality that can rally the support of a lot of people, and most importantly, a lot of young people."

The former Prime Minister said: "If Jeremy Corbyn becomes leader it won't be a defeat like 1983 or 2015 at the next election. It will mean rout, possibly annihilation. It doesn't matter whether you're on the left, right or centre of the party, whether you used to support me or hate me. But please understand the danger we are in. The party is walking eyes shut, arms outstretched over the cliff's edge to the jagged rocks below." (credit:JUSTIN TALLIS via Getty Images)

The actor said: "For me Jeremy Corbyn is our only beacon of hope to get the Labour Party back on track, get the electorate back in touch with politics and save this country from the constant mindless bullying of the vulnerable and poor. Aspirational? Surely we should all aspire that everyone living in this country has the right to a decent quality of life." (credit:Matt Crossick/Matt Crossick)

The musician said: "Corbyn has a story that people want to hear. It’s positive – idealistic even – but it isn’t outlandish, although the neoliberals would like you to think it is." (credit:Michael Crabtree/PA Archive)

The Labour grandee said: “In my view only Yvette Cooper can unite the party to win again. Those members who can’t give her their first preference should give her their second. After over a century of male leaders we have an election where the most qualified candidate to lead our party back to government happens to be a woman. Let’s end the madness and elect her.” (credit:Dominic Lipinski/PA Wire)

The scholar said: "If I were a member of the Labour Party, I would vote for Corbyn. He actually seems to have some ideological commitment, which could get the Labour Party to think about what it actually stands for." (credit:John Stillwell/PA Archive)

The film director said: ""Jeremy Corbyn, true to the best traditions of Labour, has a realistic plan to build new homes. Councils should have the power to plan and build good houses, environmentally sound, with proper infrastructure. Labour had the best Housing Minister ever in Nye Bevan. It's time for another with the same vision." (credit:Thibault Camus/AP)

The Guardian journalist said: "Labour people, motivated by the plight of the needy in a grossly unjust society, shouldn’t gamble the future of the weak on such a slender chance. Every Tory government impoverishes the poor and enriches the wealthy. Every Labour government makes landmark social progress. Winning next time matters desperately. A Cooper leadership offers an infinitely better hope of success." (credit:Ben Birchall/PA Archive)

The Guardian journalist said: "He is the very antithesis of the negative caricature of an MP: he’s defined by his principles and beliefs, uninterested in personal self-advancement, and determined to use his platform to further the interests of people and causes that are otherwise ignored."
