asked the Secretary of State for the Home Department what has been the total cost of publicity incurred by his Department in the years 1973, 1974 and 1975; and what is the estimate for 1976, broken down into relevant headings.

I regret that the information is not available in the form requested. Costs for corresponding financial years were:Britain, and of persons manufacturing explosive devices intended for such use.

No. Chief officers of police are not limited by any shortage of funds for these purposes, and both they and I believe that the introduction of a more rigid system, with all its practical disadvantages, such as was tried in Northern Ireland and then discarded in 1974, would be unhelpful.
