Lewis Hamilton retires from Chinese GP
The F1 world championship leader, needing to finish ahead of Alonso and Raikkonen to clinch the title, slips into the gravel as he enters the pit lane.
Formula One world championship leader Lewis Hamilton retired just after halfway through a wet Chinese Grand Prix on Sunday.
The 22-year-old McLaren driver, who needed to finish ahead of defending champion and team mate Fernando Alonso and Ferrari's Kimi Raikkonen to clinch the title, slipped into the gravel as he entered the pit lane.
Marshals tried in vain to push him clear.
