HC Deb 11 April 1986 vol 95 c196W
Mr. Tony Banks

asked the Secretary of State for the Home Department, pursuant to the reply of 27 March, Official Report, column 543, what additives are currently under consideration for use in the two prototype water cannon currently being assessed by the Metropolitan police.

Mr. Giles Shaw

There are no current plans to use water cannon operationally with or without additives. But as part of the assessment coloured markers are to be added to show water distribution patterns.
