WATCH: Boris Helps Nick Ferrari Do Ice Bucket Challenge

Nick Ferrari has completed the Ice Bucket Challenge - and roped in the Mayor of London to help.

Nick had been nominated by Darren Gough and Nicky Clarke for the charity challenge, so after Ask Boris, he asked the Mayor to tip a bucket of ice cold water over his head.

Nick has donated money to Motor Neurone Disease and the Mayor's Reading Fund.

He nominated his two sons and Julian Assange.

The Ice Bucket Challenge has been a viral sensation around the world, raising millions of pounds for charity.
