Inquiry casts doubt on F1 title
Kimi Raikkonen's world title has been thrown into doubt following an inquiry into the cars of BMW Sauber and Williams at the Brazilian Grand Prix.
Race stewards are investigating alleged irregularites with the cars' fuel.
Williams's Nico Rosberg was fourth in the race, followed by BMW Sauber's Robert Kubica and Nick Heidfeld.
If they were disqualified, McLaren driver Lewis Hamilton would be promoted to fourth, giving him enough points to displace Raikkonen as world champion.
