HC Deb 20 March 1995 vol 257 c42W
Mr. Allason

To ask the Secretary of State for Foreign and Commonwealth Affairs if he will declassify the wartime decrypts designated(a) ZGA, German naval attachés in Tokyo, (b) ISOS, Alwehr traffic, (c) ISK, Alwehr machine cipher traffic, and release them to the public Record Office.

Mr. Hurd

Following the release of the Dir/C archive in 1993 and 1994, GCHQ is continuing to review wartime intelligence material issued by the Government code and cykpher school. This includes the material referred to by my hon. Friend which will be reviewed in turn for possible release. One of these reports, on communications between Berlin and the naval attaché in Tokyo, is already in the Public Record Office as Z/P/ZG/248 in ADM223/4.
