Northern Ireland's Police Ombudsman has settled his dispute with the PSNI over access to sensitive police files.
Dr Michael Maguire had initiated legal proceedings, after he said he was being denied access to police information, related to 60 murders, including material about informers.
However, in a statement tonight, the ombudsman said the PSNI has now accepted that his office has a legal right to see any material it wishes during the course of an investigation.
The cases the ombudsman is examining include the deaths of six people, shot by loyalists as they watched a World Cup match on television at a Loughinisland pub in 1994.
He is also investigating the killing of an RUC officer in 1992.
It has been claimed that the RUC's Special Branch had advance notice of the attack and that at least two IRA informers were involved.
