Muhammad Ali has died at the age of 74, prompting widespread tributes to one of sport's most brilliant, bravest and original showmen.

The boxer, who was born Cassius Clay and changed his name after converting to Islam, was a frequent visitor to London and reportedly had a great affection for the city.

As well as strutting his stuff in the ring and displaying the verbal sparring skills for which he was equally renowned, he showed his softer side during his time in west London.

Archive photos show him taking a break from training in White City ahead of his 1966 fight with Britain's Henry Cooper to sign an autograph for a two-year-old.

He can also be seen surrounded by starstruck youngsters during a visit the London Free School children's play group and families' group at 34 Tavistock Crescent, in Notting Hill .

Ali died at a hospital in Phoenix, US, after being admitted on Thursday (June 2) suffering from a respiratory illness.

He won light-heavyweight gold at the 1960 Rome Olympics and went on to become the first boxer to capture a world heavyweight title on three separate occasions.

His achievements in the ring and his remarkable wit outside it, including the renowned quote "I'm so mean I make medicine sick", saw him crowned Sportsman of the Century by Sports Illustrated. He also earned worldwide admiration for his championing of civil rights.
