I believe Burlesconi had a place in Sardinia, I think he hosted then UK PM Tony Blair and his wife. Burlesconi is an interesting character on his own, with implied P2/Mafiosi contacts.

The Island of Malta may be a tax haven?, not sure, Monaco, was used as one in the past. Also, the Knights of Malta is a wing of the Jesuits of Catholic Church, which Joe Bonanno was inducted.

I think there is a pic of Bonanno inducting in the thread about Saputo.
