Londoner Billy had been all set for a life in politics. After getting a degree in international relations from Staffordshire University, he spent three years working as a political researcher in the House of Commons.

But in his spare time he had started training as a trapeze artist, and in 1992 he walked away from the day job to become a full-time professional circus performer.
