HC Deb 01 July 1971 vol 820 c182W
Mr. Money

asked the Secretary of State for the Home Department in how many cases following positive breathalyser tests, for the most recent year for which figures are available, was a motorist required to take a blood or urine test, where the analysis subsequently proved to be negative, as compared with the number of convictions for the same period.

Mr. Sharples

The information is being extracted and I hope that I will be able to let my hon. Friend have it before long.
