London: Italian Prime Minister Silvio Berlusconi's dental nurse is to face trial for arranging prostitutes for the 74-year-old leader's infamous “bunga bunga” parties, a media report said.

Prosecutors have asked for 25-year-old Nicole Minettia -- appointed regional councillor by Berlusconi who's embroiled in several sex scandals -- to be charged with hiring some 33 prostitutes for him, a daily reported.

Minetti, the former dental hygienist, is one of the three closest associates of Berlusconi facing allegations which are part of the same probe involving a teenage prostitute allegedly paid for sex by the controversial Italian PM.

Minetti is said to have procured the attractive young women for Berlusconi's after -dinner sex games played at his villa near Milan.

The prosecutors claim Minetti, who was also a former TV star, and two others recruited the girls for the parties -- all attractive TV stars, beauty queens or models and among them was belly dancer Karima El Mahroug.

The prosecutors say that at the time El Mahroug was just 17-year-old and she was paid by Berlusconi with cash and jewellery -- as were the other girls -- in return for sex.

In a statement Milan prosecutor Edmondo Bruti Liberati said: "We have requested that Nicole Minetti, Emilio Fede and Lele Mora be sent for trial on charges of procuring adult and juvenile prostitutes in Milan between September 2009 and May 2010."

Minetti, Fede and Mora all deny the charges and like Berlusconi claim the parties were innocent dinners.
