BRITISH PRIME MINISTER David Cameron has labelled comedian Russell Brand “a joke”.

With just days until the UK general election, Cameron has turned his attention to the TV host-turned-political activist, who has interviewed Labour leader Ed Miliband this week.

Miliband was spotted leaving Brand’s apartment yesterday, with a trailer for the interview going online today.

In the clip, Miliband pledges to close tax loopholes that have allowed companies like Amazon pay virtually no tax in the UK.

However, the incumbent Prime Minister was unimpressed, telling a crowd in north London that both Brand and Miliband are “a joke”.

He is funny. Right? It’s funny, but you know politics and life and elections and jobs and the economy – it’s not a joke. Russell Brand is a joke. Ed Miliband hangs out with Russell Brand – he is a joke. This is not funny. This is about the election.

“This is about our future, this is about jobs, about the economy, it is about the recovery. I haven’t got time to hang out with Russell Brand.”

Brand took aim at Cameron in response, poking fun at Cameron’s “brain fade” on Saturday, where he forgot which football team he supports, as well as his privileged background.
