Rome, April 12 - The first-day results of an online vote by former comedian Beppe Grillo's 5-Star Movement (M5S) to select a candidate for the next Italian president has been annulled after it was hacked, Grillo said on his Website Friday. Thursday's scrapped voting will be relaunched on Friday. The vote is open to M5S members who signed on before December 31, 2012. President Giorgio Napolitano's successor will be determined by a vote next week by members of parliament and 58 regional electors. "The chosen name (from the online ballot) will be the one that the M5S votes for in parliament," said Grillo Thursday.
