Giving a very personal speech at the Sovereign's Parade, marking the graduation of troops from the academy, recalling his own big day.

"It is almost 12 years ago to the day that I stood where you are.

"I remember the deep sense of pride that came from passing out of one of the finest military academies in the world."
