The Act of Loyalty also marked the 200th anniversary of King George IV's visit to Scotland in 1822, known as the "King's Jaunt", which included General Sir Robert Abercromby, the then Governor of Edinburgh Castle, presenting the castle key to the Sovereign for the first time.
[2] The Armed Forces conducted a parade and Presentation of the Key for Edinburgh Castle in the gardens of the Palace of Holyroodhouse.
[3] The Governor, assisted by three Service Cadets, then proceeded to the Equerry's Door and presented key to the Queen, saying:[4] "We, representatives of all ranks in the Armed Forces serving in Scotland, bound by our Oath to serve Your Majesty, your heirs and successors, and marking the 200th anniversary of the presentation of the key to George IV in 1822 and this 70th anniversary of Your reign, I offer this key for your acceptance to your Royal Fortress of Edinburgh Castle.
"Three cheers for the Queen were then given by members of the Armed Forces before a pipe tune composed for the Platinum Jubilee called Diu Regnare was played, as she returned to the palace.
[5] On completion of the parade, the ceremonial troops dispersed and the Key to Edinburgh Castle was returned to lie in the Great Hall.
