Italy's caretaker Premier Mario Monti says if recent elections produce a government that abandons further economic integration with Europe, Italians should vote again.

No party won a clear victory in last month's national elections, and Italy's president won't convene talks to establish the government's composition until March 20.

The center-left leader Pier Luigi Bersani is expected to get the first shot. He has ruled out an alliance with Silvio Berlusconi's forces, which leaves comic Beppe Grillo's euro-skeptic 5 Star Movement. Grillo has proposed a referendum on the euro single currency, which could hurt investor confidence.

Monti, who finished fourth, told a news conference Wednesday that it would be better to have new elections if a new government "is oriented to interrupt Italy's European path and that of reform."
