(FILES) Spanish Crown Princess of Asturias Leonor smiles during a visit of the Jardines de Albabia gardens in Bunyola, on the island of Mallorca during their summer holidays in the Balearic islands on July 31, 2023. Princess Leonor, the heiress to the Spanish crown, will swear loyalty to the constitution on October 31 on her 18th birthday, helping to turn the page on the scandal-tainted reign of her grandfather, Juan Carlos. After taking the oath Princess Leonor can legally succeed her father, King Felipe VI, and automatically becomes head of state in the event of the monarch's absence.
