Emanuele di Savoia left Italy just after the WW2. Italy opted then for the Republic and sent the King away.
Two years ago, thanks to Berlusconi, the ex-King of Italy was allowed to come back.
Today, he is in prison. Perhaps this shows that no matter what you do, or who you are, corruption is endemic in Italy when you have the right (wrong?) connections.
Le Roi est mort...Vive la Republique
