asked the Chancellor of the Exchequer what contribution has been made to Great Britain's invisible exports for the years 1957, 1958, 1959 and 1960, as a result of the operation of the special concessions granted to overseas trade corporations in Part IV of the Finance Act, 1957; and what has been the net effect of this legislation on the nation's balance of payments.

It is not possible to assess quantitatively the net effect of this legislation on the United Kingdom's invisible exports, or on the balance of payments as a whole.
