Russell Brand is the celebrity with the most negative effect on politics, according to a YouGov poll.
According to 46% of the people polled, Brand offers the most negative contribution to politics, while 41% voted for Jeremy Clarkson and 19% for U2's Bono.
In January this year, Brand called for Britons to abstain from voting in order to stage a 'revolution'.
"Give us something to vote for then we will vote for it," he said in a speech.
"Give us a system that is truly representative. Use this education that you are receiving to bring about ideas that can benefit not just you but all of us."
He has since been a guest speaker at several anti-establishment events, written a book calling for a political and private revolution, and attended Anonymous' Million Mask March.
Brand also recently said he can't rule out the possibility that the US government was behind the 9/11 terror attacks during an interview on BBC2's Newsnight, claiming he is "open-minded" about the possibility the 2001 terror attacks were an inside job.
He added: "I think it is interesting at this time when we have so little trust in our political figures, where ordinary people have so little trust in their media, we have to remain open-minded to any kind of possibility."
His friend Noel Gallagher, from the band Oasis, has since said that Brand does "talk a lot of s**t".
Clarkson, the controversial presenter of the BBC's globally popular Top Gear show, has repeatedly come under fire for allegedly sexist and racist remarks.
In July this year, Ofcom ruled that Clarkson "deliberately" used a racist term to describe an Asian man during the programme's Burma special.
Ofcom said that Clarkson's use of the word "slope" during the BBC 2 programme was offensive and in breach of broadcasting standards.
