Formula One will herald a new world champion at the end of tomorrow's Brazilian Grand Prix, only the 30th driver to claim the honour. The favourite is Britain's Lewis Hamilton, who has a seven-point lead over Brazil's Felipe Massa.

It has been a long, tough season, with many highs and lows for both drivers. Massa can claim to have had the most bad luck, with 20 points dropped through an engine failure in Hungary and a Ferrari team refuelling mistake in Singapore, when certain victories were in sight.
