F1 chief Max Mosley's son found dead

The son of Max Mosley, president of Formula One's governing body, has been found dead at his home in London, a police source said today.

Alexander Mosley, 39, an economist, was discovered by a relative on Tuesday at his house in the Notting Hill area of west London, the Sun newspaper said on its website.

"I can confirm that a man in his late 30s was found dead yesterday at an address in W11," a London police spokeswoman said. "He was pronounced dead at the scene. We are not treating this as suspicious."

A police source confirmed the dead man was Mosley's son.

The International Automobile Federation (FIA) said in a statement: "The FIA extends sincere condolences to the Mosley family on the sad news of the death of Alexander Mosley.

"Our thoughts are with Alexander's family and friends, and we would request that the media respect the Mosley family's privacy at this difficult time."

A post mortem was taking place but the Sun said the cause of death was believed to be a drugs overdose.

Last year Mosley, the FIA president, won 60,000 pounds in damages from the News of the World which was ruled to have breached his privacy by publishing details of his part in a sado-masochistic orgy.

During the court case, Mosley revealed that neither his wife of almost 50 years nor his sons knew about his interest in sado-masochism until the newspaper article.
