Racing legend Lester Piggott is in intensive care in Switzerland following the recurrence of a heart problem.

The 71-year-old, who is widely regarded as the greatest jockey of all time, is in hospital in Lausanne. It is believed that his wife Susan and daughter Maureen are by his side.

The former 11-times champion jockey, who retired from the saddle in 1994, was admitted to the West Suffolk Hospital at Christmas with a heart problem. After a stay of five days, he was allowed home.

Son-in-law William Haggas told www.telegraph.co.uk: “The latest news we have is that Lester is conscious and coherent.”
