HC Deb 21 October 1952 vol 505 c845
20. Mr. Janner

asked the Chancellor of the Exchequer to what extent information is available with regard to the amount of revenue received by this country from overseas in respect of licences to manufacture various British-patented products; and whether he will consider publishing figures dividing such revenue according to the various trades concerned.

Mr. R. A. Butler

I regret that no separate record is kept of foreign currency earnings from this source.
