HC Deb 20 March 1969 vol 780 c715
3. Mr. Dalyell

asked the Secretary of State for the Home Department when he expects to complete his review of the effects of CS smoke in cases of riot control.

Mr. Elystan Morgan

There is no intention that CS smoke shall be used by the police for controlling rioting crowds and no review is being made of its effects when so used.

Mr. Dalyell

Is no review to be made?

Mr. Morgan

No review in this connection is to be made. I should like to make it plain once again to my hon. Friend that there has been no change since the statement made by the then Home Secretary in this House on 20th May, 1965, to the effect that CS smoke would be used only for the dislodging of armed criminals or dangerously insane persons.
