An Italian judge on Tuesday ordered Prime Minister Silvio Berlusconi to stand trial on charges he paid for sex with a 17-year-old Moroccan girl, then tried to cover it up.

Berlusconi has stood trial on a number of business-related charges, but this is the first time the 74-year-old billionaire businessman is being tried for personal conduct.

Berlusconi has denied wrongdoing, accusing the prosecutors of seeking to oust him from power.

Judge Cristina Di Censo handed down the indictment with a terse statement. The trial is to begin April 6, and will be heard by a panel of three judges, all of them women.

The decision means Di Censo believes there is sufficient evidence to subject Berlusconi to an immediate trial, as has been requested by prosecutors. The sped-up procedure skips the preliminary hearing stage and is ordered in cases of overwhelming evidence.

Paying for sex with a prostitute is not a crime in Italy, but it is if the prostitute is under 18.

Berlusconi has called the accusations "groundless" and dismissed the case as a "farce."

But the indictment adds to Berlusconi's troubles at a time when the three-time prime minister is politically vulnerable following a split with an ex-ally, and will increase pressure on him to resign —- a possibility he has repeatedly rejected.

There was no immediate comment from Berlusconi. He skipped a planned appearance at a news conference in Sicily about immigration, and was returning to Rome.

"We didn't expect anything different," one of Berlusconi's attorneys, Piero Longo, was quoted as saying by the Affaritaliani website.

Prosecutors allege Berlusconi paid for sex with the Moroccan girl, nicknamed Ruby, then used his influence to get her out of police custody when she was detained for the unrelated suspected theft of 3,000 euros ($4,100).

They allege that Berlusconi feared her relationship to him would be revealed.

Both Berlusconi and Ruby have denied having sexual relations, though she has said Berlusconi gave her 7,000 euros ($9,500) on their first meeting.

The child prostitution charge carries a possible prison sentence of six months to three years. The abuse of influence charge, which experts say is more dangerous for Berlusconi, carries a possible sentence of four to 12 years.

The opposition pressed its case for Berlusconi's resignation again Tuesday. 

"Leave the premiership, let us not be the laughing stock of the world," said Alessandro Maran of the leading opposition Democratic Party. "Free Italy."

The trial brings to four the number of judicial cases Berlusconi is currently battling. They will all be starting or resuming in coming weeks, after Italy's highest court recently watered down an immunity bill his government had passed to suspend the trials.

Berlusconi is charged in a tax fraud case relating to his Mediaset media empire, and charged with bribery in another case.

Another tax fraud case, but pertaining to more recent events than the Mediaset trial, will continue with a preliminary hearing next month.

Berlusconi has always denied wrongdoing in the many cases involving his media holdings, and has either been acquitted or seen the statute of limitations expire — something that is considered likely in two of the trials now under way.

He has long contended he is the victim of a political vendetta orchestrated by what he says are left-leaning prosecutors.
