Italy's 5-Star Movement grows up with youthful new leader

ROME (Reuters) - Forget the outbursts of Beppe Grillo. To gauge the prospects of the anti-establishment 5-Star Movement listen out for the more measured tones of 29-year-old Luigi Di Maio, fast emerging as the next leader of Italy's second largest party.

The 5-Star Movement exploded onto the scene at Italy's 2013 national election when it won a stunning 25 percent of the vote, paving the way for the rise of anti-system parties around Europe, such as Podemos in Spain and Syriza in Greece.
