Declaring that this year’s title battle is a “lot more political” than Red Bull’s last endeavours, Christian Horner says the “inbox from Toto to the FIA” needs a “major clear-out”.

While Max Verstappen and Lewis Hamilton have battled on the track, the protagonists separated by two points with seven races remaining, Horner versus Wolff has been the off-track highlight.

The two team bosses have not held their punches, trading barbs in the media.

And it seems Horner, who recently admitted that he enjoys winding up Wolff, is not done.

Speaking to the PA news agency, the Brit spoke about the politics of this year’s championship, which has seen Mercedes approach the FIA to question Red Bull’s wing and then later the pit stops.
