HC Deb 19 November 1998 vol 319 c740W
Mr. Livingstone

To ask the Secretary of State for Northern Ireland in what circumstances the military and security forces in Northern Ireland have been authorised to use water cannon since 1968. [60288]

Mr. Ingram

Water cannons were withdrawn from service by the Royal Ulster Constabulary in December 1969 and have not been used since. Records are not available as to their usage prior to that time.
