Muhammad Ali has died at the age of 74

Muhammad Ali has died at the age of 74, a family spokesman has said. The former world heavyweight boxing champion, one of the world's best-known sportsmen, died at a hospital in the US city of Phoenix, Arizona, after being admitted on Thursday. He was suffering from a respiratory illness, a condition that was complicated by Parkinson's disease. The funeral will take place in Ali's hometown of Louisville, Kentucky, his family said in a statement.

Born Cassius Marcellus Clay, Ali shot to fame by winning light-heavyweight gold at the 1960 Rome Olympics. Nicknamed "The Greatest", the American beat Sonny Liston in 1964 to win his first world title and became the first boxer to capture a world heavyweight title on three separate occasions. He eventually retired in 1981, having won 56 of his 61 fights.
