Rome, April 2 - The head of Italy's center-right People of Freedom party (PdL), Angelino Alfano, on Tuesday said there was little room for dialog with Pier Luigi Bersani, the leader of the center-left Democratic Party (PD). Following Bersani's refusal to compromise with the PdL in efforts to form a new government, Alfano said: "If Bersani wants to occupy all the institutions, there is no space for dialog". Failed government-forming efforts by Bersani, whose center-left alliance won a majority of seats in Italy's lower house but failed to win a majority in the equally powerful upper house in inconclusive national elections at the end of February, have lead to calls by the PdL for new elections. On Tuesday Alfano repeated calls for new elections: "If this stall continues because the PD is thinking for itself rather than for the nation, there is only the road of elections as soon as June. "In our constitutional order, parliament has the obligation to express a majority and a government. If it does not (do so), the word must be returned to the voters. There are no other roads," Alfano said.
