Jake Humphrey presents coverage of qualifying for the Singapore Grand Prix. With just five races remaining in the 2010 season, there is little room for error at the Marina Bay street circuit. So far this season Red Bull have dominated qualifying, although drivers Sebastian Vettel and Mark Webber have not always reproduced that pace on race day. Britain's Lewis Hamilton, who won this race last year, will also be one to watch, as will McLaren team-mate Jenson Button, who needs a strong end to the year if he is to retain the drivers' championship.
