Lester Keith Piggott was an English professional jockey and trainer. With 4,493 career flat racing wins in Britain, including a record nine Epsom Derby victories, he is widely regarded as one of the greatest flat racing jockeys of all time and the originator of a much-imitated style. Popularly called "The Long Fellow", he was known for his competitive personality, restricting his weight and, on occasion, not sparing the whip, such as in the 1972 Derby. Piggott was convicted of tax fraud in 1987 and sentenced to three years in prison. He served just over one year.

A jockey is someone who rides horses in horse racing or steeplechase racing, primarily as a profession. The word also applies to camel riders in camel racing. The word "jockey" originated from England and was used to describe the individual who rode horses in racing. They must be light, typically around a weight of 100–120 lb., and physically fit. They are typically self-employed, and are paid a small fee from the horse trainer and a percentage of the horse's winnings. The job has a very high risk of debilitating or life-threatening injuries.
