A blind woman claims she was refused entry to the British Grand Prix at Silverstone because her guide dog was a "health and safety" risk.
Kate Young, 51, had been planning the trip for months, but was left feeling "crushed" after being told that someone could fall over her golden retriever, Star, when she rang up a week before to say she would be taking the dog.
Mrs Young, from Cheshire, was told that dogs were not allowed in and so she stayed at home while her family enjoyed the day out.
But she later heard that celebrities were allowed to take their pets inside, including Lewis Hamilton, who took his bulldogs, Roscoe and Coco, along.
The F1 star posted photographs of his dogs on Twitter, writing: "Love having my best buddies here with me at the British GP, Silverstone."
Mrs Young said: "I felt completely stonewalled. Without my guide dog I am completely dependent on others, and in the two years since I've had Star this is the first time I've felt so restricted."
Guide Dogs campaign officer, Helen Honstvet, said:
A spokeswoman for Silverstone said their rules about animals at the British Grand Prix are set by the Motor Sports Association.
