Almost a third of complaints in cases closed by the European ombudsman in 2016 were about transparency, the ombudsman said in her annual report, published on May 24. The ombudsman closed 86 inquiries last year that were about transparency, such as complaints about access to documents. The EU institution on which the ombudsman opened the most inquiries was the European Commission, with 144. European Ombudsman Emily O'Reilly said at a press conference that the Commission topped the list because of "the institutional role it plays in the EU."
