Rome: Young women attended "inelegant" dinner parties at former Italian premier Silvio Berlusconi's luxury homes for personal gain and even had lesbian sex in the hope of stirring his desire to sleep with them, judges in Italy have ruled.

"In most cases, the women just hoped they would reap economic or other personal benefits, while some had longer-term career plans to transform their extremely modest lives," the judges in the southern Italian city of Bari said late on Wednesday.
