Bah, youtube pulled the footage. A short clip is here
Doubt it will come to anything but theres a lot of speculation about it going on... some people saying Vergne backed off, so Vettel had to go past. Yet, Vettel used KERS to assist the move, suggesting he needed the extra pace to achieve the overtake.
Also read rumours online that Red Bull knew they'd broken the rules, and asked Vergne to finish at least 20 seconds behind Vettel in case the race result was altered by the stewards (Vettel would *just* keep the championship by dropping to 7th). Looks like Vettel coasted the last run over the line - Vergne ended up 19.2 seconds behind at the flag. Sneaky stuff going on???
Either the FIA make a statement saying the result stands, or I can see this one dragging out, appeal process etc etc.
