Why did Princess Leonor and Infanta Sofia not attend the funeral of Constantine of Greece?

Last January 16 took place the funeral of Constantine of Greece, this unfortunate event brought together almost the entire Spanish royal family, but the big absentees were the Infanta Sofia, 15, and her older sister Princess Leonor, 17, why did they not attend?

To say the last goodbye to her brother, Queen Emeritus Sofia of Greece, had the support of her family: her husband King Juan Carlos I, her children King Felipe, the Infantas Elena and Cristina, her grandchildren also attended except for Leonor and Sofia.

Why Princess Leonor and Infanta Sofia did not attend the funeral of King Constantine II?

Apparently the absence of the daughters of the King and Queen of Spain was due to academic commitments. Princess Leonor did not want to interrupt her studies in Wales. Recall that the heiress returned in early January to UWC Atlantic College in Wales to continue the last stage of the second year of baccalaureate.

For her part, the Infanta Sofia has not interrupted her studies and remained in Spain. The youngest daughter of the King and Queen is studying the 4th year of ESO at the Santa María de los Rosales school.

The absence of Leonor and Sofia in the funeral ceremony of the last king of Greece, for academic reasons was very striking since their cousins the Urdangarin and Marichalar did prefer not to attend their schools, universities and jobs to travel to Athens and accompany Sofia of Greece in her grief.

For some experts in royalty the absence of the Princess of Asturias and her sister Sofia is due more to a privacy motive on the part of the kings of Spain who have limited the exposure of their daughters, being very different from how the childhood, adolescence and youth of King Felipe and his sisters were managed, who related perfectly with the ‘cousins’ of the different monarchies.
