Rome , Italy ( CNN ) -- Prosecutors in Italy allege that a businessman supplied Prime Minister Silvio Berlusconi with about 30 women , or escorts , in order to win favor with him . It 's the latest development in a long-running sex scandal . Transcripts of some of 100,000 wiretap recordings made between September 2008 and 2009 were filed with a court in the southern city of Bari Friday , as prosecutors wrapped up a three-year prostitution investigation . The transcripts reveal that Berlusconi and businessman Gianpaolo Tarantini repeatedly discussed bringing women to parties . Tarantini selected women to be of `` young age and slender '' and instructed them in what to wear and how to behave at Berlusconi 's parties , the prosecutors say . Among them was Patrizia D'Addario , prosecutors say , who in 2009 alleged she and other women were paid to attend parties at Berlusconi 's residence . He denied her claim . In another conversation , they discuss what women they should each bring to a party that night . Berlusconi says that the male guests are powerful men `` so the girls have the idea of being in front of men that can decide their destiny . '' He says he has `` two young girls whom I 've not seen for a long time '' -- one of them a journalist and the other a 21-year-old Brazilian `` who cried over the phone telling me that I 'd forgotten her . '' Discussing a party the night before in a wiretap from October 10 , Berlusconi tells Tarantini there were perhaps too many women . `` At the most to have two each , but now I want you also to have yours , otherwise I feel in debt . Why do n't you bring yours for you and I bring mine . ... `` Tarantini agrees , and Berlusconi continues : `` Then we can exchange them ... `` In a conversation between Tarantini and one of the women he recruited , she said Berlusconi told her he would help her . Berlusconi is not accused in this case filed in Bari but faces a separate trial in Milan for allegedly paying for sex with a then-17-year-old Moroccan belly dancer named Karima el Mahroug , nicknamed `` Ruby the Heart-stealer . '' El Mahroug has denied having sex with the premier . Both admit that he gave her money , although they say it was an act of kindness to help her . Berlusconi has always denied wrongdoing and also denies ever having paid for sex . The latest revelations in the Bari case have reignited calls among his critics for Berlusconi to resign . In a letter published Saturday to the Foglio newspaper , run by his former spokesman Giuliano Ferrara , Berlusconi wrote that he had no intention of quitting . He said his behavior was nothing like what had been described in the media , and that he had done nothing to be ashamed of . In a separate but linked investigation by prosecutors in Naples , Tarantini is accused of having blackmailed Berlusconi over the scandal . According to the Naples prosecutors , Berlusconi was a victim of `` veiled and implied threats '' and paid 800,000 euros to Tarantini . The prime minister denies having been blackmailed and says he gave the money to Tarantini as an act of charity . CNN 's Livia Borghese contributed to this report .
Newly filed court documents reveal details of inquiry into associates of Berlusconi . Transcripts show Berlusconi and businessman Tarantini often discussed girls . Berlusconi is not charged in the case and has always denied wrongdoing . He faces other trials , one over allegedly paying an underage girl for sex .
