Legendary runner Sir Roger Bannister has been diagnosed with Parkinson's disease.
The former athlete, 85, who famously became the first man to run a four-minute mile in 1954, is struggling to walk after battling the illness for three years.
The star, who worked as a neurologist after hanging up his running shoes, tells BBC Radio Oxford, "I am having trouble walking. Ironically it is a neurological disorder - Parkinson's. I have seen patients with so many disorders that I am not surprised I have acquired an illness."
