Italian Prime Minister Mario Monti handed in his resignation Friday to President Giorgio Napolitano, the Italian government press office said. The move comes after Parliament approved a budget by a vote of 309-55, with five abstentions, said ANSA, the state-run news agency. Monti will outline his plans Sunday but will not say until afterward whether he plans to run in elections expected to be held February 24, ANSA said, citing "sources."
