MILAN - Three aides to ex-Italian Premier Silvio Berlusconi have gone on trial on charges they allegedly recruited an underage Moroccan girl and other women for prostitution at Berlusconi's villas.

After a brief hearing Monday, Judge Anna Maria Gatto immediately adjourned the trial until Jan. 20.

The three aides -- Emilio Fede, an executive in Berlusconi's media empire; Nicole Minetti, a local politician and former showgirl, and talent agent Dario "Lele" Mora -- are accused of recruiting women for prostitution and abetting prostitution, including of a minor.

They deny wrongdoing.

Berlusconi is being tried separately for allegedly paying for sex with the Moroccan girl, charges he denies. He faces a hearing in that case Wednesday, the first since he resigned as premier.
