Information Liaison Department
The Information Liaison Department was a part of the psychological operations activity of the British Army in Northern Ireland from around 1970 until it was disbanded and replaced by the Information Policy Unit in around September 1971.
According to Paul Foot in his book Who Framed Colin Wallace:
- In 1970 on the orders of the Ministry of Defence, the information department of the Army in Northern Ireland was reorganised. Tony Staughton remained in charge of public relations, with Colin and Colonel Yarnold in support. side by side, a new unit was set up entitled Information Liaison - later Information Policy - commanded by a military officer with the rank of lieutenant colonel. The first of these was Lieutenant colonel Johnny Johnston. He was swiftly replaced by a hard-line paratroop officer, Colonel Maurice Tugwell. Information Policy was a separate unit working for the intelligence services but expected to operate under the cover of public relations. Its function was psychological warfare.
A submission by counsel to the Bloody Sunday Inquiry described the role of INQ 1873 (the designation given to a witness at the inquiry who gave evidence anonymously) in psychological operations as follows:
- 2.1 Lieutenant Colonel INQ 1873 was sent to Northern Ireland in October 1970 in order to run the Information Liaison Department. He was an expert in psychological operations in combat situations [Day 242/7] and was responsible for psychological operations in Northern Ireland under the direction of the CLF [Day 242/52]. In or about September 1971 the Information Liaison Department was disbanded and replaced by the Information Policy Unit.
- 2.2 Colonel Tugwell arrived in Northern Ireland on 30 August 1971 to become head of the Information Policy Unit. INQ 1873 was appointed his deputy. Tugwell said that he was sent to Northern Ireland at short notice because, so General Carver told him, there was a crisis in confidence about Army public relations [Day 240/60].
