Berlusconi may face six years' jail over sex charges Documents presented to the court showed that in the three years since the alleged sexual encounter, Berlusconi, a billionaire media executive, gave Ms Mahroug more than $5.8 million. The prosecution of former prime minister Silvio Berlusconi on charges of paying for sex with an under-age prostitute and then abusing his powers to cover it up concluded on Monday with a call for a six-year jail sentence and a lifetime ban from public office. Prosecutor Ilda Boccassini said Mr Berlusconi was aware that Karima el-Mahroug was a minor when he had sex with her. Ms Boccassini said Ms Mahroug, known as Ruby Heart-Stealer, was "part of a system of prostitution organised to satisfy the pleasure of Silvio Berlusconi" at parties held at his villa outside Milan while he was in office. Documents presented to the court showed that in the three years since the alleged sexual encounter, Mr Berlusconi, a billionaire media executive, gave Ms Mahroug more than $5.8 million. Karima el-Mahroug. Both Mr Berlusconi and Ms Mahroug deny they had sex. The court is expected to announce a verdict on June 24. The outcome could affect Italy's fragile three-week-old government, which is made up of an uneasy alliance of Italy's largest centre-left party and Mr Berlusconi's right-leaning People of Liberty party. Another court upheld a tax fraud conviction against Mr Berlusconi last week. A decision by government ministers from Mr Berlusconi's party to attend a demonstration in Brescia on Saturday to protest at the rulings against him strained the nascent coalition. After the demonstration, Prime Minister Enrico Letta warned his centre-right allies that he was not prepared to keep the government alive at any cost. Italy's highest court is expected to rule on the tax case this year. Defence lawyers in the Mahroug case will deliver their closing arguments on June 3. In a recent TV program, Ms Mahroug denied she had ever been a prostitute. She had initially lied about the facts in the case - including pretending to be a niece of former Egyptian president Hosni Mubarak - to make herself seem more important. Mr Berlusconi said when he tried to get Ms Mahroug released from prison after she was stopped on accusations of theft, it was because he believed she was related to the Egyptian leader.
