Legendary jockey Lester Piggott has died aged 86, his son-in-law has said.
Piggott, who won the Epsom Derby nine times, had been in hospital in Switzerland.
During a career lasting almost 50 years he rode nearly four and-a-half thousand winners.
He rode his first winner, The Chase, at the age of 12 at Haydock in 1948.
His final win was on Palacegate Jack on the same course in 1994, a few weeks before his 59th birthday. He retired in 1995.
Piggott was crowned champion jockey 11 times between 1960 and 1982 and was inducted into the British Champions Series Hall of Fame last year.
In 2007, he was admitted to intensive care because a heart problem had recurred, but made a swift recovery.
