Jake Humphrey presents live coverage of qualifying for tomorrow's Belgian Grand Prix, as Formula 1 returns after a month-long summer break. Red Bull Racing's Sebastian Vettel has been on pole seven times this year but it is his team-mate Mark Webber who leads the championship standings. British title rivals Lewis Hamilton and Jenson Button will be hoping that their McLarens fare better than they did last time out in Hungary; Button could only qualify in eleventh place while Hamilton failed to complete the grand prix.
