(see related stories) Rome, December 21 - The chief of Italy's biggest trade-union confederation, the left-wing CGIL, on Friday cast doubt about whether it would be legitimate for Premier Mario Monti to run in upcoming elections. Former European commissioner Monti, who has been at the helm of an emergency government of unelected technocrats since November 2011, is expected to announce in the next few days whether he will stand for office. "I cannot say whether it is appropriate or inappropriate," CGIL chief Susanna Camusso replied when asked about whether Monti should run "I will limit myself to saying that it would be the first time in the history of the country that a government without a popular mandate uses the effects of the policies from that period of government for an electoral campaign. "I believe that it is not within the normal democratic rules of this country," Camusso added. Camusso also accused Monti of not defending workers' rights, particularly with respect to Fiat, which is in a bitter dispute with the CGIL's metalworkers arm FIOM. Monti visited a Fiat plant on Thursday.
