Princess Irene of Greece, the younger sister of Queen Sofia, has died at the age of 83, the Spanish palace has confirmed.
In a statement seen by HELLO!'s sister publication, HOLA!, the royal household said: "Their Majesties the King and Queen and Her Majesty Queen Sofia regret to announce the passing of Her Royal Highness Princess Irene of Greece at 11:40 a.m. today at the Zarzuela Palace in Madrid."
It comes after Queen Sofia cancelled engagements in Palma de Mallorca this week to be by her sister's side after a decline in her health. HOLA! revealed three years ago that Princess Irene was "suffering from cognitive impairment that has progressively weakened her".
