Italy's centrist Azione to join forces with PD for election-source

ROME (Reuters) -Italy's centrist Azione party will enter an alliance with the larger Democratic Party in next month's national election, an Azione party source said on Tuesday, in a move seen boosting the centre-left's chances in the vote.

Italy's election law favours parties that form broad alliances. The ballot is set for Sept. 25 and polls show a conservative alliance is on course for victory.
