Boris Johnson plays wheelchair rugby

The Mayor of London launched the World Wheelchair Rugby Challenge by having a go at the sport nicknamed "murderball" for its highly competitive atmosphere.

The event will be held in October 2015 at the Copper Box arena in the Olypmic Park in east London.

"It's huge to get wheelchair rugby going in the Copper Box. We had a wonderful Paralympic Games, and people may remember all the tickets suddenly flew out the window as soon as people realised how exciting it was.

"Wheel chair rugby is possibly the most violent, the most exhilirating game you can specate at," said Boris Johnson.
