Zephaniah self-identifies as an anarchist. He appeared in literature to support changing the British electoral system from first-past-the-post to alternative vote for electing members of parliament to the House of Commons in the Alternative Vote referendum in 2011. In a 2017 interview, commenting on the ongoing Brexit negotiations, Zephaniah stated that "For left-wing reasons, I think we should leave the EU but the way that we’re leaving is completely wrong".
