After breaking free from a pack of title contenders, Fernando Alonso's task at the British Grand Prix is to ensure that advantage in the Formula One championship isn't now thrown away.

The season had produced seven different winners from the opening seven races until Alonso halted the record-breaking run by becoming the first driver to take the checkered flag twice in 2012.

With a 20-point lead over Red Bull's Mark Webber established at the European GP, Alonso returns to the Silverstone circuit where he won for a second time last year.

But with showers forecast for race weekend in central England, in this most unpredictable of seasons the result could be even harder to predict on Sunday.
