HC Deb 13 December 1932 vol 273 c177
18. Mr. MITCHESON

asked the President of the Board of Trade whether he can make any estimate of the amounts of what, in contradistinction to invisible exports, may be called invisible imports arising from payments made in the form of licences and royalties on patent rights controlled abroad?

Dr. BURGIN

The information available is insufficient to enable any such estimate to be framed.
