The Rugby Football Union is coming under renewed pressure from the players' union to publish the findings from their investigation into the leaked World Cup reports.
Damian Hopley, chief executive of the Rugby Players' Association, is giving a presentation to the RFU council on Friday during which he will call for the document to be made public.
Hopley is frustrated that "no-one has been brought to book" over the damaging leaks, and he called on the RFU's new chief executive Ian Ritchie to ensure the issue is not swept under the carpet.
The damning reports laid bare the inside story of England's "doomed" World Cup campaign, painting the picture of a disunited squad with some players accused of being more interested in money than glory.
The investigation into the leak, conducted by strategic intelligence company Monitor Quest, was inconclusive but one of the 25 people who had access to the reports refused to co-operate.
"The Monitor Quest report has not been made public, we believe it should be made public," Hopley said. "There is a responsibility for the game to actually understand what went on and for the facts to come out.
"There were 25 people who had access to the report via the 12 people on the Professional Game Board and their secretaries. One person has not been interviewed. We would like that person to come forward and be interviewed.
"We feel let down by the process. Our frustration is the lack of accountability. We are looking for a final outcome of this. Whether that means nothing will be done but the report will be published is a step forward from our point of view. But just to let it fade into the background is not acceptable."
A Twickenham spokesman sought to explain why it would not be published, saying: "The Monitor Quest report is a confidential document. While it is not for publication it has been shared in full with the PGB, the RPA and Premiership Rugby.
"It was produced by a highly reputable organisation and while no specific individual was identified as responsible for the leaks, it did make important recommendations about document control and information security which we are determined to learn from."
