Former Formula 1 world champion Sir Jackie Stewart has been taken to hospital after falling ill on a London-bound flight from Geneva.
The 71-year-old was given first aid by air stewardesses after complaining of chest pains.
Paramedics met Stewart at London Heathrow airport and are thought to have taken him to Hillingdon hospital.
“He did pass out and as a precaution he was taken to hospital to be looked at,” his eldest son Paul told BBC Sport.
“I’ve just spoken to him in hospital. He seemed absolutely fine but obviously something happened and we need to establish what, but I’m on my way to see him right now.
“I should think he’ll just be checked over and hopefully it will be nothing more sinister than that.”
Stewart won 27 Grands Prix and three F1 world titles during his career.
