The Queen guitarist decided against running as an independent candidate in the U.K. general election in May (15), and instead set up activist organisation Common Decency to call for a reform to the British political system.

The huge poster unveiled by May in Vauxhall, south London, reads, "Sick of the lies? You have one voice - one vote - use it!!!... #CommonDecency... Join our campaign - we can reclaim our democracy."

In a video posted on YouTube.com, May encourages Brits to vote on 7 May (15), and adds, "We can turn Britain upside down and we can get a decent Parliament. We can bring back democracy. We can reclaim our right to have a voice in this country."

May acknowledges his initiative is similar to comedian Russell Brand's calls for political reform in his book Revolution, telling Mirror.co.uk, "There's plenty of reasons not to like Russell Brand, and I understand that, but whether or not you like him I think everyone should read that book because he does speak the truth. He's a very important part of what's going on."
