Rome, April 17 - An angry representative of the Democratic Party (PD) charged Wednesday that his colleagues were being bombarded by emails urging them to vote a rival politician as the new Italian president. "For several hours now a cyber attack has been underway in the form of serial emails sent to mailboxes of PD members of parliament to support the candidacy of Stefano Rodota'," said PD Senator Federico Fornaro. His complaint came just hours after Rodota', 82, agreed to stand as presidential candidate for the anti-establishment 5-Star Movement of comedian Beppe Grillo. Rodota' is a constitutional lawyer, former head of Italy's privacy authority and former Communist and centre-left MP. Fornaro said he didn't think Rodota' had anything to do with the email storm. Lawmakers from the Lower and Upper Houses of parliament along with representatives of Italy's regional governments will begin voting for President Giorgio Napolitano's successor on Thursday. Rodota has been seen as a candidate who may also be able to garner support from parts of the PD.
