Gaetano Badalamenti, once known as the “boss of bosses” of the Sicilian Mafia, has died at the age of 80 in the US, where he was serving a prison sentence for drug trafficking.

Former Italian premier Giulio Andreotti was formally acquitted of charges that he ordered the Mafia killing of a journalist in 1979, with the country’s highest court wiping out a previous conviction of the veteran politician.
