An Italian judge has sent the prime minister Silvio Berlusconi for trial on charges of abuse of power and having sex with a minor.
The date for the case has been set for 6th April.
The judge, Cristina Di Censo, followed the advice of prosecutors, who accuse Berlusconi of paying for sex with an underage Moroccan dancer.
They also say the prime minister put pressure on police to release the young woman after she had been arrested, suspected of theft.
Berlusconi has denied any wrongdoing, saying the investigations against him are politically motivated.
Ruby, the woman at the centre of the scandal, has appeared in a commercial for a book, wearing a bikini.
She also denies accusations that Berlusconi paid for sex with her.
Pressure on the prime minister has been mounting. On Sunday thousands of women demonstrated in Milan, calling for his resignation.
