HC Deb 20 June 1940 vol 362 c266W
Mr. Stokes

asked the First Lord of the Admiralty whether he will make provision so that the widest possible publicity may be given in scientific papers to detail drawings of the German magnetic mine so that every advantage may be taken by scientists in this country of adapting its principles and details for other purposes?

Mr. Alexander

No, Sir. The hon. Member's proposal would entail revealing to the enemy the knowledge we possess of his weapons. Scientists outside the Government service who are qualified to assist in these matters are kept fully informed of developments.
