The main official papers dealing with the State's response to the outbreak of violence in Northern Ireland in 1969 will be released for inspection today.
The papers became a source of controversy earlier this week after the chairwoman of the National Archives Advisory Council, Ms Margaret MacCurtin, said they were missing and an investigation would be carried out.
The files, Partition - Government Policy, were not released with other State documents from 1969 under the 30-year rule on January 1st. It subsequently emerged that they had been transferred from the Department of the Taoiseach to the National Archives in 1996 "for safekeeping".
Officials at the Northern Ireland division of the Department of the Taoiseach have examined the papers to ensure that the material released does not pose a national security risk.
The papers, which contain seven files, deal with policy on the North from September 1968 to November 1969.
There were serious differences of opinion within the Fianna Fail government, led by Mr Jack Lynch, over its approach to developments in the North in the 1968-70 period. Those differences were eventually to become public in 1970 with the dismissal from cabinet of Mr Charles Haughey and Mr Neil Blaney over the arms-smuggling affair.
The files will be released to the media today and will be available to the public from Monday.
