Red Bull boss Christian Horner hit back in the ‘bendy wing’ saga by casting doubt over the legality of Mercedes’ front wing.

The storm has been brewing ever since Lewis Hamilton commented on the rear wing of the RB16B after qualifying in Spain.

“The Red Bulls are really fast on the straights. They have this bendy wing on the back of their car which they put on today and they gained at least three tenths from this wing,” he said back at the Circuit de Barcelona-Catalunya.

Since then the FIA have announced that new tests on the rear wings will be introduced from the French GP, but that has sparked negative reactions from the likes of McLaren and Red Bull’s title rival Mercedes.
