Since reaching prominence he has branched out, writing a newspaper column and presenting documentaries about boats and planes - and hosting a chat show.

Other irons in the fire

He has also been holding talks with BBC bosses about making other programmes.

The BBC said Clarkson might still return to Top Gear occasionally but the show will be seeking to replace him as principal presenter.

Clarkson told The Sun: "It has been my life and I'm very sad but I decided it was time for a change.

"I've been lying awake thinking about it ever since I made the decision. It's a very big move to take. But I'd taken Top Gear as far as I could."

Wheels make wealth

He said his favourite memory was of spending a week in Italy test driving Ferraris, Lamborghinis and Bugattis.

"I remember thinking life doesn't get much better than this for someone who loves cars," he said.

Clarkson, a father-of-three, began his career as a local newspaper reporter but switched to car magazines before being chosen to present Top Gear in 1991.

He now owns a home in Fulham, west London, as well as a mansion in the Cotswolds.
