McLaren F1 team principal Martin Whitmarsh is usually a measured kind of guy when it comes to dishing out criticism to rivals, but he certainly did not mince his words on Sunday on the subject of Sebastian Vettel after the young Red Bull driver slammed into Jenson Button’s car, probably not only ruining his own world championship chances but also those of the reigning title holder.

In a stinging critique of Vettel  - which many felt was fully justified on this occasion – Whitmarsh laid into his team’s rival and at the same time in effect questioned whether the penalty for his serious driving error was sufficient, given the consequences for Button. But to be fair to Whitmarsh, his observations seemed prompted more by frustration than anger on a day when Lewis Hamilton had driven a beautiful Belgian GP to win at Spa for the first time.
