Muhammad Ali has died aged 74, a family spokesperson has confirmed.
The one-time world heavyweight boxing champ - probably the most famous sportsperson the world has ever known - passed away at a hospital in Phoenix, Arizona, after being admitted on Thursday. He had been suffering from a respiratory problem, an illness complicated by his Parkinson's disease,
and was on life support for the past 24 hours.
The sad news has produced an enormous outpouring of reaction and tributes from leading figures across all fields. His former opponent George Foreman led the way:
