No one ever accused Italian Prime Minister Silvio Berlusconi of not speaking his mind.

In a sign of his frustration at the investigations into his alleged crimes and misdemeanours, Silvio Berlusconi vowed in July to leave Italy, which he described as a “shitty country” that “sickened” him.

The Italian prime minister’s astonishing remarks are contained in the transcript of a telephone conversation secretly recorded by police investigating claims he was being blackmailed about his sex life.

So why does he stay?
