The charges arose from Berlusconi's trial for paying for sex with an exotic dancer known as Ruby the Heart-Stealer when she was under 18. He was initially convicted but acquitted on appeal, the judge saying he could not have known she was a minor.

The billionaire businessman has beaten numerous criminal charges over the years with his only conviction to date being one for corporate tax fraud, which led to him being kicked out of parliament.
Even if convicted there is little chance of him ending up behind bars because of Italy's restrictions on penal sanctions against the elderly.
