Bob Geldof's never one to shy away from a fight and this time he's really upped the ante.

A bizarre clash between pro and anti-Brexit campaigners is taking place today on London's Thames river, as Bob Geldof boarded an 'IN' boat to oppose Nigel Farage's pro-Brexit flotilla that's making its way towards parliament.

Geldof's boat has apparently been blasting out songs including Chicago's "If you leave me now", while the 'Leave' boats retaliated by firing water from a hose at them.

All of the action has been captured on Twitter.
