Christian Horner and Red Bull have been plunged into a fresh crisis following a dramatic leak of secret evidence from the investigation that cleared him of inappropriate behaviour towards a female colleague.
A cache of material made up predominantly of screengrabs from WhatsApp exchanges between Horner and his accuser, including images, was sent from an anonymous email address to hundreds of journalists who have reported on the case.
The dossier of evidence was also sent to Liberty Media as well as Formula 1 chief executive Stefano Domenicali.
The leak came as Horner’s arch-rivals questioned the outcome of the investigation that cleared him amid calls for the FIA to launch its own probe into the affair.
