Italian center-left leader Pier Luigi Bersani says he'll take another 48 hours to seek support for a new government after failing to persuade the anti-establishment 5 Star Movement to back him.

Bersani said Wednesday that Italy needs a government now. But the 5 Star Movement said its lawmakers will not back any established party.

The movement's leader, Beppe Grillo, described the main political party leaders with an off-color term on Twitter and blamed them for robbing young Italians of their future.

Bersani's coalition controls the lower house but not the Senate. He has excluded seeking a deal with former premier Silvio Berlusconi's center-right forces.

If he fails, the president can tap someone else to try to create a government or he can call for a new election.
