This comes days after the revelation that Prince Harry is planning to leave the Army to continue his mother's legacy with a number of charitable projects during his second 'gap year'. Speaking  about his choice to bring his active military career to an end, he said it was a 'really tough' decision and he was looking forward to starting a new chapter in his life.

'He cared deeply about the sport and gave so much to both the eventing and wider horse world. Thank you for all the wonderfully supportive letters and messages and many apologies for only answering a small number of them so far.'
