Silvio Berlusconi's defence lawyers have named Hollywood star George Clooney, the Italian foreign minister and a bevy of showgirls as witnesses at the premier's upcoming prostitution trial.
Prosecutors, for their part, have asked to hear from 136 witnesses, including the Moroccan teenager at the centre of the scandal and 32 other women who allegedly worked as prostitutes during parties at Mr Berlusconi's villa, according to Italian news reports.
Both sides presented their lists of witnesses at the Milan tribunal where the trial opens next week. A judge must now decide which witnesses to admit.
Mr Berlusconi, 74, is accused of having paid for sex with the Moroccan, who is known as Ruby and was 17 at the time, and then using his influence to try to cover it up. The premier denies wrongdoing.
Clooney was listed because Ruby once said she had seen the actor and his Italian girlfriend Elisabetta Canalis at one of Mr Berlusconi's parties, according to the law firm representing Mr Berlusconi.
"We want to see if they confirm this fact or not," said lawyer Piersilvio Cipollotti.
But in a statement, Clooney said: "It seems odd since I've only met Berlusconi once and that was in an attempt to get aid into Darfur." The American actor has campaigned to raise awareness about the humanitarian crisis in the western Sudanese region.
Italian newspapers reported months ago that Ruby had said Clooney, who has a mansion on Lake Como north of Milan, and Ms Canalis were guests at one of Mr Berlusconi's parties. According to a February 22 report in leading Italian newspaper Corriere della Sera, prosecutors talked with Ms Canalis last month and she denied that she and Clooney had attended any of the premier's parties.
Mr Berlusconi's defence also listed foreign minister Franco Frattini and other Cabinet officials amid the 78 people named as witnesses, Mr Cipollotti said. Mariano Apicella, the Neapolitan composer who performs for Mr Berlusconi, as well as showgirls and TV personalities who frequented his parties were also named, according to the ANSA and LaPresse news agencies.
Ruby, whose real name is Karima el-Mahroug, was 18 in November.
Mr Berlusconi is accused of having had several sexual encounters with her between Valentine's Day last year to May 2, in exchange for money. The premier is also accused of abusing his influence when he called police in May to get Ruby out of custody in Milan, where she had been held for an unrelated theft. She was eventually released.
Prosecutors say the premier wanted to keep his sexual relations with the girl secret. Mr Berlusconi has said he intervened because he believed Ruby was the niece of now ousted Egyptian president Hosni Mubarak and wanted to prevent a diplomatic incident.
According to news reports, prosecutors have also cited as witnesses Milan police officials involved in Ruby's brief detention, as well as three Berlusconi associates also under investigation in the scandal: an ex-showgirl and Mr Berlusconi's dental hygienist recently elected at a local post with the premier's party; a TV agent; and TV newscaster and long-time Berlusconi friend.
Mr Berlusconi says he plans to attend hearings of the trial, which opens on April 6, as much as his official duties allow. He also faces two other trials and a possible indictment relating to his business dealings.
