HC Deb 19 March 1940 vol 358 c1829W
Mr. Bartlett

asked the Minister of Economic Warfare what is the reason for the suspension of the issue of navicerts for the shipment of lubricating oil from the United States of America to Belgium, Holland, and Denmark; and what is the nature of the guarantees he obtained against the re-export of the surplus to Germany?

Mr. Cross

The temporary suspension of the issue of navicerts covering lubricating oil was due to the comparatively large stocks which have been accumulated by certain neutral countries adjacent to Germany, though I have no evidence that any appreciable quantity of oil has found its way into Germany. The Governments of the countries concerned have prohibited entirely the export of such oils to belligerents.
