Charlotte Dujardin, one of Britain’s most decorated Olympians, has confirmed that she is withdrawing from the Paris Games after “making an error of judgement” that was caught on video.

The six-time dressage medallist admitted that she is under investigation by the International Federation for Equestrian Sports (FEI) and will withdraw from all competitions.

The three-time Olympic champion claimed that the investigation stemmed from a video that took place during a “coaching session” and she is “deeply ashamed”.

Releasing a statement via her Instagram, Dujardin wrote: “A video has emerged from four years ago which shows me making an error of judgement during a coaching session.

“Understandably, the International Federation for Equestrian Sports (FEI) is investigating and I have made the decision to withdraw from all competition – including the Paris Olympics – while this process takes place.

“What happened was completely out of character and does not reflect how I train my horses or coach my pupils, however there is no excuse. I am deeply ashamed and should have set a better example in that moment.

“I am sincerely sorry for my actions and devastated that I have let everyone down, including Team GB, fans and sponsors.

“I will cooperate fully with the FEI, British Equestrian Federation and British Dressage during their investigations, and will not be commenting further until the process is complete.”

Dujardin won team and individual gold medals at the London 2012 Games on Valegro, before the pair went on to win individual gold and team silver four years later in Rio. At the Tokyo Games, she won two bronzes on a different horse, Gio.

The 39-year-old needed just one more medal to eclipse now-retired cyclist Dame Laura Kelly and become Britain’s most decorated female Olympian.

She had been due to compete in both the individual dressage and team event alongside Carl Hester and world champion Lottie Fry.

“It will be one of the most incredible moments if that does happen,” she said on the cusp of making history, before confirming her withdrawal.

“But I don’t put any pressure on myself to make that happen.”

The dressage competition at Paris 2024 begins on July 30 and will be held at the iconic Chateau de Versailles, with the opening ceremony on Friday.
