Red Bull urged to 'tell the truth' or face F1 exclusion

McLaren CEO Zak Brown has called on Red Bull staff members to sign affidavits in order to bring an end to cheating accusations.

During the United States Grand Prix weekend, Red Bull confirmed it has a device that allows it to alter the front bib height of the RB20 following scrutiny from rival teams.

Red Bull insisted it has not operated the device between qualifying and the grand prix as that would be illegal.

FIA single-seater director Nikolas Tombazis conceded it would be difficult to analyse when it was specifically used at previous events.

In an attempt to put the matter to bed, Brown has requested Red Bull staff sign legal documents declaring the system was never used in a manner that could be considered outside the regulations.

"I'd like to see the senior leadership, the former chief mechanics and the current mechanics sign an affidavit stating that they have never used or have no knowledge of it being used," Brown told the Daily Mail.

"The suggestion in the pit lane from a handful of people is that it has been used in that manner, so the only way to bottom it out is the old-fashioned 'sign here', stating what has gone on.

"I know if I was presented with an affidavit and the consequences of not telling the truth were severe, I'd tell the truth."

Browns calls for 'deterrent' Red Bull penalty if guilty

McLaren is currently embroiled in a title fight with Red Bull and lead the Milton Keynes-based team by 39 points in the constructors' championship.

Lando Norris is also attempting to close down a 54-point gap in the drivers' standings.

As the teams continue to push for supremacy on the track, Brown warned Red Bull should face serious punishment if it is found to have acted outside the regulations with the device. 

"It [a penalty] needs to be a deterrent," Brown warned.

"We have seen drivers excluded from races and championships. And I am not saying Max should be excluded, by the way. 

"We have seen teams excluded from races and championships. If, and I say if, parc fermé rules have been broken, the penalty needs to be of that magnitude, depending on whether they did it once or have been doing it regularly for three years. 

"There must be consequences."
