Italian actor and comedian Beppe Grillo, co-founder of the Five Star Movement (M5S) party, mourned on Thursday the loss of Dario Fo, who passed away at age 90. "Today Dario Fo has left us. We'll remember him by his speech in Piazza Duomo in Milan on February 19th 2013, when he told us with his mighty voice: 'You do it!'. You will always be with us Dario", Grillo wrote on his blog after learning the news of the passing of the 1997 Nobel Prize in Literature recipient. Fo announced his support to M5S in 2013.
