One of Britain’s most decorated female Olympian, Charlotte Dujardin, has pulled out of the Paris Games after a video emerged showing her in what she called “making an error of judgement” during a coaching session.

The 39-year-old dressage rider, who has won three Olympic golds, including two in London in 2012, was set to compete in both the individual and team events in France later this month.

Referring to the video, the Team GB athlete said what happened was “completely out of character” and “does not reflect how I train my horses or coach my pupils”, but she said, “there is no excuse” and she was “deeply ashamed” and “sincerely sorry”.

She has since been suspended and under investigation by the British Equestrian Federation and British Dressage as well as International Federation for Equestrian Sports (FEI) and ordered to “withdraw from all competition – including the Paris Olympics, while this process takes place”.

In a statement on her Instagram, she said: “A video has emerged from four years ago which shows me making an error of judgement during a coaching session.”

She continued: “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 will co-operate fully with the FEI, British Equestrian Federation and British Dressage during their investigations, and will not be commenting further until the process is complete,” she went on.

Ms Dujardin has won a total of six Olympic medals in her career, making her Britain’s joint-most decorated female Olympian of all time, tied with retired cyclist Dame Laura Kenny.
