Boxing legend Muhammad Ali has died today at the age of 74.

The former heavyweight champion was hospitalised in Arizona this week after suffering from respiratory problems that had reportedly been made worse by his diagnosis of Parkinson’s disease in the 1980s.

Before his death, he led a stellar career that spanned 21 years with 56 wins and Olympic Gold to his name.

Tributes have since poured in for Ali from world leaders, CEOs as well as former boxers.

Here’s what they’re saying.
