asked the Secretary of State for Northern Ireland if he will list the materials known to have been used to manufacture the home-made explosive material used in Northern Ireland by terrorists and seized by the security forces in Northern Ireland since 1 January 1983, and which such materials are available for sale in Northern Ireland in significant quantities through normal commercial outlets.
There are a number of substances which can be used to produce improvised explosives. For security reasons, I do not believe it would be right if I were to list these.
asked the Secretary of State for Northern Ireland what weight of explosive material, believed to be in the possession of a terrorist organisation, was seized by the security forces in Northern Ireland in each month since 1 January 1983 to the latest coŉvenient date; and of that explosive material how much was of commercial origin and how much home-made.
I shall reply to the hon. Gentleman as soon as possible.
