Annabel said: “I have dreamed of representing my country in this event for many years, so to receive the call last week to say I had been selected was just incredible.
“The selection process has been extremely tough, involving applications, interviews and selection days.
“The assessment team considers everything—not simply your performance in the individual events but your proficiency with horses, riding qualifications and, more generally, how well you would represent this growing sport as an ambassador.

“I cannot wait to represent the UK and compete on the international stage in Australia this summer.”
