Rome, January 2 - A commission of inquiry into the fall of Silvio Berlusconi's government 13 months ago is an "interesting" if odd idea, Premier Mario Monti said Wednesday. "Berlusconi confuses me on a logical level," Monti added during an interview on the RAI radio show Radio Anch'io. "I hope the voters are less confused than me". As campaigning heats up for next month's election, Berlusconi pledged Wednesday that if he is re-elected as Italian premier, he would hold a parliamentary inquiry into the international "plot" that led to the fall of his government in November 2011. Early elections were called for February 24-25 after Berlusconi's party withdrew its support from Monti's technocratic government in parliament. Berlusconi resigned 13 months ago as Italian borrowing costs hit unsustainable levels, demonstrating that international financial markets had lost all confidence in the country's economy.
