Raikkonen 'may leave F1'

Departing Ferrari driver Kimi Raikkonen revealed he may walk away from Formula One if he cannot land a competitive drive for next season.

The Finn, who pipped Lewis Hamilton to the world championship in 2007, will be replaced at the Italian team by double world champion Fernando Alonso after the Spaniard's switch from Renault on a three-year deal was confirmed yesterday.
