Mr Berlusconi praised his government in its fight against the mafia
Italian Prime Minister Silvio Berlusconi has vowed to defeat organised crime in the country by 2013.
"The mafia is a pathological phenomenon that we want to defeat once and for all by the end of this term in office," Mr Berlusconi told Italy's national radio.
"No government in the history of the republic has acted with as much determination and efficiency in the fight against criminal organisations".
Italian police have arrested hundreds of people in recent anti-mafia raids.
Those being held are accused of extortion, arms dealing and drugs trafficking.
