§ Mr. Robert McCartney
To ask the Secretary of State for Northern Ireland what discussions he has had with the Government of the Irish Republic in respect of formulating joint security measures to deal with a breakdown in the ceasefire. 
§ Sir John Wheeler
The Government regularly discuss security matters with the Government of the Republic of Ireland, but it would be inappropriate to reveal the nature and scope of such discussions. However, I can assure the hon. Member that the security forces on both sides of the border have maintained excellent co-operation and will continue to do so.
