Italian anti-immigrant party hoping for gains in regional vote seen as test for PM Renzi

Italians were voting for governorships in several regions and posts in dozens of municipalities in what is being seen as a partial test of Premier Matteo Renzi's grip on his oft-squabbling Democratic Party.

Six regions were voting on Sunday. In Sicily, voters could cast ballots on both Sunday and Monday.

Balloting in Liguria, traditionally a stronghold of the left, could indicate how deep runs the resentment of Renzi's leadership, seen as heavy-handed by some prominent Democrats. Among the several governorship candidates are two from the left: one from his party and another who could attract disgruntled Democrats.

In the northern Veneto region, the anti-immigrant Northern League is hoping for gains as Italy struggles to shelter tens of thousands of migrants arriving by sea on smugglers' boats.
