HC Deb 12 November 1917 vol 99 c4
6. General CROFT

asked what is the total value of dyes bought from abroad since the beginning of the War, and from what countries they were imported; what is the tonnage of prime materials exported to neutrals from this country to convert into dyes since the beginning of the War; what is the tonnage for prime materials for which a licence has been issued for transit to Switzerland since the restriction of imports and exports; and what is the amount of tonnage for export of prime materials to Switzerland for which licences have been issued or applied for in the coming six months?


I think that it would be contrary to the public interest to give the details asked for, which would convey important information to the enemy.
