Rome, December 17 - A magistrate from Palermo could be the candidate for prime minister for a coalition of centrist parties to be announced December 21. Antonio Ingroia, who on Monday asked the governing body of Italy's magistrates to be put on "electoral leave", will explain his political platform at a conference in Rome Friday. In a 10-point manifesto published ahead of the Rome conference, Ingoria said his centrist 'Io ci sto' movement aims to "re-launch Italy finally freed of mafias and corruption". Among those supporting Ingoria's bid to lead a civic list are the current mayors of Naples and Palermo, Luigi de Magistris and Leoluca Orlando, respectively, as well as the head of the Italy of Values (IdV) party, former 'Bribesville' magistrate Anotnio Di Pietro. "We of Italy of Values have given our availability to participate," Di Pietro said Monday.
