asked the Prime Minister whether he has any information showing that a super-submarine, more powerful than any yet built, has been or is being constructed in Germany; and, if so, if he can make any statement on the subject?

The PARLIAMENTARY SECRETARY to the ADMIRALTY (Colonel Sir James Craig)

I have been asked to reply to this question. The answer is in the negative.
