Security 50. Mr. Biggs-Davison asked the Secretary of State for Northern Ireland what progress has been made with cross-border co-operation with the Republic of Ireland's security forces. Mr. Humphrey Atkins I am satisfied with the progress made in implementing the measures agreed with Irish Ministers on 5 October. Security considerations preclude my giving specific details, but I am confident that the measures will add to the effectiveness of the common campaign against terrorism and to the two Governments' already extensive co-operation.
