After a career spanning more than 60 years, Sir Stirling Moss - widely regarded as the best driver never to win an F1 title - has announced his retirement from competitive racing.

The 81-year-old made the announcement that he is to bring his glittering career to an end following qualifying for the Le Mans Legends race, where he was due to share driving duties in a Porsche RS 61 with Ian Nuthall.

"This afternoon I scared myself and I have always said that if I felt I was not up to it or that I was getting in the way of fellow competitors, then I would retire.

"I love racing, but now it is time to stop."

Moss made his debut in F1 back in 1951, finishing second in the standings on four occasions and winning 16 times in 66 starts.

Between 1954, the season Moss considered as his first with a 'proper' Formula 1 machine, and 1962, Moss took part in 318 races in a range of different disciplines - winning more than half.

After a crash at Goodwood ended his competitive F1 career Moss went on to become a regular figure in historic motorsport events and has also lent his voice to the popular children's television show Roary the Racing Car in recent years.
