HC Deb 07 February 1968 vol 758 c113W
69. Mr. Gresham Cooke

asked the President of the Board of Trade why the glass component of the breathalyser phials, as used by the police, is not made in this country instead of West Germany.

Mrs. Gwyneth Dunwoody:

The source of the glass component is a matter for the manufacturers; we cannot require the incorporation of British tubes.
