No sex with Berlusconi, says boyfriend

Italian Prime Minister Silvio Berlusconi did not have sex with an 18-year-old at the centre of a scandal that has wrecked the conservative leader's marriage, the teen's ex-boyfriend said.

In a letter to Italy's Corriere della Sera newspaper, Luigi Flaminio apologised for having talked publicly about Berlusconi's relationship with Noemi Letizia.

"Now they are insinuating that he had sexual relations, something which I rule out. [It] is impossible knowing Noemi and her values."

He said his remarks to La Repubblica had been used to attack Berlusconi.
