The publication of the Kenova report has moved a step closer after passing through security checking.
The interim report focuses on the findings of Operation Kenova, the investigation into the alleged activities of the person known as Stakeknife.
Kenova Lead, former Chief Constable Jon Boutcher said: “I am pleased to announce that the Kenova interim report has now passed national security checking with no changes or redactions.
"It has now been provided to the Public Prosecution Service of Northern Ireland (PPS NI) to assess whether the report is prejudicial to any possible future prosecutions.
"I anticipate this will be a relatively expeditious process and, once complete, will be able to provide a further update on the progress of the report to publication."
Kenova has also taken on several other investigations and reviews since its inception. Operation Mizzenmast, the murder of Jean Smyth-Campbell in 1972 and Operation Turma, the murder of three RUC officers on Kinnego Embankment in 1982 and The Barnard Review – a review into what has become known as the Glenanne Gang series – will each be reported on separately in the future.
