SOVIET UNION FEATURES IN U.K. GRAIN EXPORTS The Soviet Union featured prominently in U.K. Grain exports outside the EC for the period July 1/March 13, taking a combined total of 1.10 mln tonnes of wheat and barley out of all-destination U.K. Exports of 7.16 mln tonnes, the Home Grown Cereals Authority said, quoting provisional Customs and Excise figures. The Soviet total comprises 634,000 tonnes of wheat and 472,000 tonnes of barley. Grain traders said the figures understate shipments already made by several thousand tonnes and they expect total U.K. Grain exports to the USSR this season to reach 2.5 mln tonnes, comprising 1.5 mln wheat/1.0 mln barley.
