Horner vs Whitmarsh: McLaren's wings flexing most

Christian Horner has hit back at claims Red Bull were slowed down at Spa-Francorchamps due to succumbing to the flexible wing saga.

McLaren's Jenson Button had said before leaving Belgium that the pace of the previously dominant RB6 had been "affected" by the more stringent deflection test, with the new floor tests to possibly have "even more of an effect" at Monza next weekend.

Button's boss Martin Whitmarsh, and Mercedes' Ross Brawn, also said they thought the front wings on the Red Bull and Ferrari cars were flexing less visibly than they had in Hungary earlier in August.
