Italy centre-left tensions rise as Renzi cries foul over vote

ROME (Reuters) - Italy's centre-left alliance showed new signs of division on Wednesday after the chief rival to Democratic Party leader Pier Luigi Bersani denounced the party hierarchy as efforts to form a government enter a critical phase.

The deadlock has left the euro zone's third largest economy with only a caretaker government in charge as it slides further into a recession that many analysts expect will last until at least next year.
