Nicola Zingaretti was elected as head of Italy's center-left Democrats (PD) in a primary vote on Sunday.

The 53-year-old moderate will be tasked with revitalizing a party that has been plagued by infighting and diving popularity since last year's election defeat to a coalition led by the far-right League.

Zingaretti, the governor of the central Lazio region that encompasses Rome, won 65-70 percent of the vote, with more than 1.5 million ballots cast, according to an initial tally released late Sunday. 

Zingaretti tweeted his thanks to his supporters, saying it was "now time to turn the page."

Popularity problem

The PD, Italy's largest opposition party, was in government for five years before losing power in the March 2018 national election. The defeat triggered the resignation as party leader of former prime minister Matteo Renzi.

The party is currently polling at 18.2 percent, according to Italian pollster YouTrend. By comparison, the governing right-wing League party is on 35.9 per cent, while its coalition partner, the anti-establishment 5-Star Movement, is on 21.2 per cent.

The ruling coalition has struggled with internal divisions over policy and flagging economic growth — factors the Democrats will be hoping to capitalize on as they attempt to woo voters ahead of European parliamentary elections in May. In another negative development for the government, tens of thousands of people attended a massive rally in Milan on Saturday to denounce the anti-migrant policies of the League.
