WIltshire event rider Laura Collett is seriously ill in hospital after a fall at the British Eventing Horse Trials in Hampshire.
The 23-year-old, who is based at the Membury Estate, came off her horse during the event at Tweseldown Racecourse.
A statement on her official website reads: "Laura had a comfortable night and remains in a stable condition. Will keep you updated. Her family appreciate all the support from friends and well wishers".
Collett had been training legendary racehorse Kauto Star in dressage after the record-breaking steeplechaser, from Paul Nicholl's Ditcheat stables, retired last year.
