Changes in the Royal Household
When a new monarch ascends the throne, it is customary for certain Officers of the Royal Household to resign their posts, to enable the new monarch to exercise his constitutional right to organise his Household, taking due account of the public interest (article 41 of the Constitution).
The Officers in question include the Grand Master of the Royal Household, the Chief of the Military Household, the Principal Secretary to the Queen, the Treasurer, the Master of Ceremonies, the Marshal of the Court, the Comptroller of the Royal Palaces, the Crown Equerry, the Director of the Royal Archives and the Director of Human Resources.
