The Order of the Garter – Britain’s oldest and most senior Order of Chivalry – is celebrated annually with a procession and service in the grounds of Windsor Castle. This year’s service will take place on Monday, June 17.

The Office of Master of the Horse dates back centuries and was originally responsible for the Sovereign’s horses, carriages and, as a historic consequence, travel arrangements.

Now largely ceremonial, the role remains titular head of the Royal Mews. The Master of the Horse is present when the Royal Mews supports State occasions, for example, the current Master of the Horse, Lord de Mauley, rode in the Coronation Procession of His Majesty The King. The holder of the role rides on Trooping the Colour.

The role of Chancellor is among the highest-ranking titles in the Order and was held by The Bishops of Salisbury and Oxford for nearly 500 years.

Both appointments are in The King’s gift and are effective from Tuesday, June 18.
