Christian Horner back in F1 paddock amid scrutiny over his Red Bull future

Horner’s future is again in the spotlight after hundreds of WhatsApp messages appearing to be written by him to a female colleague were leaked.

On Wednesday, Horner was cleared to continue as Red Bull team principal following an internal probe into “inappropriate behaviour” by the F1 team’s parent company Red Bull GmbH. He has always denied the claims.

But just 24 hours later, messages and a number of images apparently exchanged between Horner and the complainant were sent from an anonymous email account to 149 members of the F1 paddock – including FIA president Mohammed ben Sulayem, F1 CEO Stefano Domenicali and the grid’s nine other team principals, as well as members of the media – on the eve of this weekend’s season-opening Bahrain Grand Prix.

Horner said in a statement: “I will not comment on anonymous speculation, but to reiterate I have always denied the allegations.

“I respected the integrity of the independent investigation and fully cooperated with it every step of the way.

“I remain fully focused on the start of the season.”

On Friday, Horner (50) was seen speaking to a Formula One official at the front of Red Bull Racing’s hospitality suite.

F1 and its governing body, the FIA, are considering whether to get involved in the controversy that’s engulfed the sport.
