A sporty solicitor left paralysed after falling on his head during a mountain biking course is suing a cycling instructor.

Asif Ahmed paid £79 for a beginners' course in the Surrey Hills cyclists' paradise four years ago but now faces the rest of his life in a wheelchair.

The qualified bio-technologist, engineer, barrister and solicitor hit his head after hurtling over the handlebars on notorious Holmbury Hill.

Now Mr Ahmed, 47, of Greenwich, is suing instructor, Leon MacLean, of Norwich, over the March 2012 tragedy.

But Mr MacLean denies claims that he used a "lazy form of teaching" or that "his instruction on this occasion was woefully inadequate".
