SAO PAULO, July 29 (Reuters) - Prosecutors in Brazil said on Wednesday former Petrobras executive Renato Duque had unfairly favored Italy's Saipem SpA on a contract for an undersea gas pipeline for the Lula and Cernambi offshore subsalt fields.
The accusations came in an e-mailed statement of charges for Duque, who is already on trial for corruption, and four other people. (Reporting by Caroline Stauffer; Editing by David Gregorio)
