Palermo, April 8 - Former anti-mafia magistrate Antonio Ingroia could take the helm of Sicily's tax collection authority, it emerged on Monday. Regional governor Rosario Crocetta met with the former Palermo prosecutor and leader of the left-wing Civic Revolution party "for a coffee" allegedly to discuss the proposal and the announcement of the appointment could come shortly. Riscossione Sicilia Spa, the tax collection authority, is controlled by the Sicily region. Last month the magistrates' self-governing body CSM proposed posting Ingroia to the northwestern city of Aosta should he decide to return to the judiciary after his disappointing foray into politics. Formed last December Civic Revolution performed poorly in February general elections, returning no seats in the Italian parliament. Prior to running for elected office Ingroia served briefly as head of a UN project on narcotraffic in Guatemala. His decision to go into politics sparked controversy on grounds of alleged political bias within the magistrature.
