Sep.7 (GMM) Lewis Hamilton's victory at the Belgian grand prix has been thrown into doubt, with news not only that stewards are probing an incident, but also that Ferrari has lodged an official protest.



Shortly after the championship leader took the chequered flag at the end of a frenetic finish to the 44-lap race at Spa-Francorchamps, it emerged that FIA officials would investigate his earlier battle with Kimi Raikkonen.



While the stewards are probing the Bus Stop chicane and La Source incident, it is believed Ferrari have also taken exception to a separate element of Hamilton's racing tactics.
