Berlusconi vows inquiry into 2011 fall of government, criticizes Monti's campaign about-face

Former Italian premier Silvio Berlusconi smiles as he arrives at Milan's central train station, Italy, Saturday, Dec. 29, 2012. Italian Premier Mario Monti announced Friday he is heading a new campaign coalition made of up centrists, business leaders and pro-Vatican forces who back his "ethical" vision of politics, aiming for a second mandate in office if his fledging reform movement wins big in parliamentary elections. Monti was appointed premier 13 months ago after his scandal-plagued predecessor Silvio Berlusconi failed to stop Italy from sliding deeper into the eurozone debt crisis.

Ex-Premier Silvio Berlusconi has sharply criticized the decision by Mario Monti to run in Italy's general elections and has vowed to launch a parliamentary inquiry into the 2011 fall of his government and appointment of Monti as Italy's premier.

Berlusconi spoke out Saturday after Monti ended a week of hedging and announced Friday that he would head a coalition of centrist forces, businessmen and pro-Vatican forces running for office in Feb. 24-25 elections.

Berlusconi said he never expected Monti would reneg on his repeated assurances that he "wouldn't use the public prominence as head of a technical government for an ulterior presence in politics."

Monti was named to lead a technical government after Berlusconi was forced to resign amid Italy's slide into the eurozone's debt crisis.

Berlusconi's party trails in the polls.
