Christian Horner came out fighting in Texas yesterday, insisting he is ‘appalled’ by rivals accusing Red Bull of cheating — claims he said had resulted in his staff’s children being bullied at school. Red Bull’s case is that the FIA changed interpretations of the regulations after they submitted their accounts in March. For a fellow competitor to be accusing you of cheating, to accuse you of fraudulent activity is shocking. It is understood Red Bull claim the overspend is related to non-track areas such as catering, sick pay and gardening leave. ‘Our view is that our relevant costs are within the cap,’ said Horner.
