The Duke of Cambridge has represented Her Majesty the Queen as Reviewing Officer for the first time at the Sovereign’s Parade at the Royal Military Academy at Sandhurst today.
Prince William inspected the parade and presented awards including the Sword of Honour, the Overseas Sword and the Queen's Medal.
The former graduate of Sandhurst served seven-and-a-half years in the military and trained at the Academy 12 years ago.
The Sovereign Parade takes place at the end of each term and marks the passing out from Sandhurst of officer cadets who have completed the Commissioning Course.
In 2017, the Prime Minister Theresa May represented the Queen at the ceremony.
This year, 169 officer cadets from the UK and 25 cadets from 19 other countries took part in the parade which celebrates the completion of a year's intensive training.
William's brother the Duke of Sussex attended the parade last year, eleven years after his own graduation from Sandhurst.
It was during Prince Harry's visit to Sandhurst that Kensington Palace announced the date and location of his wedding to the now Duchess of Sussex.
Prince William gave up his military career in 2013 to concentrate on his royal duties.
During his time in the forces, he worked as an RAF search and rescue pilot.
Prince Harry served in the Army for ten years, rising to the rank of Captain and undertaking two tours of Afghanistan.
