The Royal Household of Spain, officially Household of His Majesty the King (Spanish: Casa de Su Majestad el Rey), is the constitutional body whose primary function is to provide aid and support to the King of Spain in the exercise of his royal duties and prerogatives. These include his role as head of state and as commander-in-chief of the Spanish Armed Forces. It functions as the king's executive office.
The household is under the direct authority of the King, who personally selects the individuals he chooses to aid him in his constitutional duties. It is a constitutional institution, as laid down in Spain’s constitution of 1978. While the household is part of Spain’s governmental structure, it is not under the control or influence of any other state institution. The household ensures that the King has the independent means to perform all of his state functions. In particular, it is not under the administrative control of the prime minister or the Council of Ministers. The only authority to whom it answers is the King himself.
