Nick Vivarelli International CorrespondentSilvio Berlusconi, the billionaire media-mogul-turned politician who defined a three-decade-long era in postwar Italy during which TV spin, tainting allegations of corruption and sex scandals were pervasive — but who also achieved unprecedented political stability in the country — has died. He was 86. Berlusconi died at the San Raffaele hospital in Milan, according to Italian media reports. He had been suffering from leukaemia and had recently developed a lung infection.After building a fortune by launching Italian private TV with his Mediaset empire, Berlusconi entered politics in 1993, was elected prime minister in 1994, and went on to serve as the country’s premier three times, not consecutively, becoming the longest serving democratically elected Italian leader. He was ousted from parliament in 2013 following a tax fraud conviction.
