59. Mr. Gresham Cookeasked the Secretary of State for the Home Department how many breathalyser tests were made by the police in the period October, 1967 to June, 1969; and what proportion of the resulting tests disclosed alcohol blood content of 150 milligrams per 100 millilitres and over.
§ Mr. Elystan MorganDuring that period the police in England and Wales required 91,190 breath tests under Section 2(1) and (2) of the Road Safety Act, 1967. It is not possible to relate the figures for breath tests directly to those of the analyses of blood or urine specimens subsequently given; but during the same period there were 41,110 cases in which persons required to undertake breath tests under the Act later provided specimens of blood or urine which were analysed, and in 17,775 of these cases the64W alcohol concentration indicated was over 150 mgs. per 100 mls.
