Rome, March 27 - Pier Luigi Bersani, the head of Italy's center left, said Wednesday he will report back to President Giorgio Napolitano on his progress in drumming up support to form a government on Thursday. "My intention is to bring my findings on Thursday," said Bersani. Some had speculated that the Democratic Party (PD) chief would need until Friday. Bersani was handed a government-formation mandate last Friday by the president after emerging from elections late February with a majority in the House but not in the Senate, leaving a hung parliament. He has spent the past week meeting with parties in an effort to forge a working coalition, even though that seems increasingly unlikely given the refusal to compromise from the anti-establishment 5-Star Movement (M5S) of Beppe Grillo. "The (parties) in parliament are taking their time to reflect," said Bersani, "and tomorrow I expect a conclusive response".
