"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. He quit earlier this month after Berlusconi pulled his party's support from Monti's government, but is now continuing in a caretaker role until the next elections. (AP Photo/Luca Bruno)"
