(ANSA) - Rome, November 18 - A poll by the Ixè agency said Friday that that the 'No' vote in an upcoming constitutional referendum on December 4 holds a 42% to 37% lead over the 'Yes' among likely voters.

Turnout will be around 62%, according to the survey commissioned by the Agorà program of State broadcaster Rai3.

A poll released by Ixè a week ago showed a 40% to 37% lead for the 'No' vote.

According to the survey released on Friday, 77% of voters of the Democratic Party (PD) of premier Matteo Renzi said they would vote in favor of the cabinet's landmark reform to streamline Italy's cumbersome political machinery.

A reported 74% of voters of the anti-establishment Five-Star Movement (M5S) will vote against the reform, along with 72% of those backing the rightwing opposition Northern League party, Ixè said.
