Christian Horner’s Formula One future is back in the spotlight after WhatsApp messages appearing to be sent by him have been leaked.

On Wednesday, Horner was cleared to continue as Red Bull team principal following an internal probe by the F1 team’s parent company Red Bull GmbH.

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

It is unclear at this stage whether the alleged exchanges, which have been seen by the PA news agency, formed part of the investigation – of which Horner was cleared of “inappropriate behaviour” towards a female colleague – or whether it is new evidence.

Horner has always denied the claims.

The PA news agency has approached Red Bull Racing for comment, and is also trying to confirm if the exchanges are genuine.

Horner, 50, was on the Red Bull pit wall on Thursday for both practice sessions.

Speaking on Sky Sports earlier on Thursday, he said: “I am pleased that the process is over, and I cannot comment about it.

“I am here to focus on the grand prix and the season ahead and trying to defend both of our titles.”

Horner added: “I can’t give you any further comment, but the process has been conducted and concluded.

“I am pleased to be here in Bahrain, and with the team, focused on the season ahead. Within the team it (the unity) has never been stronger.”
