Even with the title as F1's newly-crowned youngest ever world champion, Lewis Hamilton says he has no plans to endorse a new official biography.

Even with the title as F1's newly-crowned youngest ever world champion, Lewis Hamilton says he has no plans to endorse a new official biography.

The McLaren driver was heavily criticised last year, when not six months into his formula one career, a publisher paid him $2m for the rights to his life so far.

'My Story' was issued in November for about $40, but it emerged earlier this year that copies were being sold in bargain bins for $2.

Hamilton now admits publishing a biography at the age of 22 was a mistake.

"I won't be doing another one for 20 years," he promised to The Times newspaper.
