Mr. Cohen

To ask the Secretary of State for Defence what liquid was sprayed from the Hawker Hunter that undertook mock chemical attacks on air defence bases during Exercise Elder Forest; how much of this liquid was used during Exercise Elder Forest; if this liquid was non-toxic; and if he will make a statement.

Mr. Freeman

During Exercise Elder Forest, a total of some 1,600 gallons of ordinary mains water was used to simulate chemical attacks upon a number of Royal Air Force stations in order to test the effectiveness of their defences against this threat.
