At the start of Q3 Alonso was second in line, ahead of Raikkonen.
Yes, and Raikkonen was right up his back. There is no way that Hamilton could have slowed enough to let Alonso past without letting Raikkonen past.
It was a stitch up. The FIA then somehow failed to prevent Hamilton's title in a fit of pique in 2008, before getting Ron Dennis out of F1 in the aftermath of the second great McLaren stitch up, Liegate.
Put it this way, if every driver who has ever lied to stewards was disqualified from a race, there'd have been more than 1 case of this happening in 61 years!
