This is very sad. I can't say that I feel bad for Vittorio Emanuele, because if this is true, and I am inclined to believe that it is, he brought it upon himself. I feel bad for his wife, Marina Doria, as well as his son, daughter-in-law, and granddaughter.
Regarding the incident at the wedding of The Prince of Asturias, Vittorio Emanuele began arguing with his cousin, The Duke of Aosta, and Vittorio punched his cousin. His cousin fell and was caught by HM Queen Anne-Marie of the Hellenes. HM King Juan Carlos I reportedly stormed out of the palace (the Palacio Real in Madrid) shouting "nunca mas," which translates to "never again." That is what I had heard.
