Defending Formula One champion Sebastian Vettel won the Belgian Grand Prix on Sunday to strengthen his overall lead with seven races remaining.
Vettel started from pole to win his seventh race of the season and 17th of his career. The German led Red Bull to a 1-2 finish with Mark Webber finishing close behind. McLarens Jenson Button started way down in 13th spot,but he caught Fernando Alonso near the end to take third place. Lewis Hamiltons slim title hopes took a further blow as he crashed his McLaren early on to slip to fifth in the standings.
Sutil among points
A double-points finish slipped out of Force Indias hands as Adrian Sutil finished seventh and Paul di Resta 11th,just outside the points bracket.
