After initially working as a hotel page boy, he started his racing career as an apprentice with Ron Smyth, who was a trainer in Epsom.
He will be best remembered as the jockey who won the 1,000 Guineas, 2,000 Guineas, Epsom Oaks (twice), Coronation Cup, and Prix de l'Arc de Triomphe.
Most watchers of the sport of horse racing would consider that his greatest moment came in 1971 when he rode Mill Reef to win The Derby.
