File photo dated March 18, 2007 of Prince Vittorio Emanuele and Emanuele Filiberto of Savoy attends a ceremony to commemorate the last italian monarchs of Savoia Family at Hautecombe Abbey in Saint Pierre de Curtille, France. Prince Vittorio Emanuele and his son, Prince Emanuele Filiberto, want to change a medieval law which stipulates that the royal line can only pass down to male heirs. But they face opposition from a rival branch of the dynasty. Prince Emanuele Filiberto, the grandson of Italy’s last king, has two daughters but no son and wants the line of succession to pass down to his oldest girl, Vittoria, who is about to turn 16.
