A court in Palermo convicted the governor of Sicily, Salvatore Cuffaro, of helping a Mafia boss by providing him with confidential investigator’s information, sentencing him to five years in prison and banning him from holding public office. Mr. Cuffaro, who was re-elected two years ago, while his trial was under way, said he would continue as governor while an appeal is in progress. In Italy, convictions are not considered final until all appeals are exhausted; the process can take years.
