In Spain, the Royal Family is only the official Royal Family. The rest are the King's Family. The institution that works for the King is the House of His Majesty the King.
Elena and Cristina have not been full-time royals, they have had private jobs and the money they received was not a salary, but a compensation for the expenses of the events they attended. Their husbands did not have a title on their own,could not represent the Crown alone, nor did they receive any payment for accompanying their wives.
Duke, about the visit to the Christ of Medinaceli, it has always been an event of the King's Family (Pilar and Margarita also attended in the past) , more than an official event of the Royal Family. It is never included in the official agenda, but they always place the photos on the web although they may not do so. The other two events that Elena has attended this year, one was because she is still Honorary President of the Paralympic Committee and another because she works for the Mapfre Foundation. Elena, as Pilar and Margarita did occasionally, may represent the King in some event, but generally they are minor acts, more related to monarchical traditions.
King Felipe has tried to organize things in accordance with the laws and provide the organization with more transparency ... but on many occasions it seems that his parents are not making it easy, when contradictions arise they usually arise from the fact that some members of the family does not accept that things have changed. It seems that in some cases he must reach agreements, so that they do not create more problems.
About Victoria ... she has turned 18 and now the press knows more about her life. She goes a course behind what corresponds to her and has changed school, it seems that she is having some problems with her studies. She has a supposed boyfriend or close friend, a bullfighter who is a friend of her brother, and it is usual to see her in the bullring and at the racecourse. Last week a video appeared of her with the bullfighter trying to fight a small cow, and it has been published that she went to the party that Vox (the extreme right political party) did in a nightclub in Madrid. The image of the children of Elena, is that of rich and privileged children, with little interest in studies and many interest in parties and outdated traditions.
