The Formula One world champion Sebastian Vettel has won the Bahrain Grand Prix for the second straight year to extend his overall championship lead to 10 points after four races.
The race took place amid controversial political circumstances, but it was untroubled by protests and Vettel cruised to victory by 9.1 seconds over the Lotus of Kimi Raikkonen who remains second in the championship.
The 25-year-old German was so far ahead after 25 of the 57 laps he was able to make a pit stop and rejoin the race still in the lead.
The Frenchman Romain Grosjean finished third for Lotus, his first podium of the season, to complete the same top three as last year.
The British pair Paul Di Resta and Lewis Hamilton were fourth and fifth, and Mexico's Sergio Perez was sixth.
