ROME (Reuters) - Italy's 5-Star Movement voted over the weekend in favour of a proportional electoral system, raising the chances of an unprecedented autumn parliamentary election.

On Sunday, 5-Star's supporters overwhelmingly backed a proportional law modelled on that of Germany, in which parties must win at least 5 percent of the national vote to get into parliament. It called for a national election on Sept. 10.
