(ANSA) - Rome, March 31 - Comedian Beppe Grillo's anti-establishment 5-Star Movement (M5S) has again stretched its lead over the ruling centre-left Democratic Party (PD), a new poll said Friday.

The M5S is up another 0.5% to 28.4% while the PD edged up 0.1% to 26.5%, said the weekly Ixè poll for Raitre.

The PD was ahead of the M5S until a recent split by leftwingers.
