asked the Secretary State for the Home Department, in banned list the export of uranium hexafluoride, pressure gauges and other equipment used in the manufacture of ultra-centrifuge plants in November; and if this was a consequence of the failure of the Dutch partners in URENCO to inform the British Government of Dr. Abel Qader Khan's activities until the summer of the current year, over three years after he had left Holland.
[pursuant to his reply, 14 December 1979]: In answering on 14 December the question from the hon. Member for Salford, East (Mr. Allaun) about the reasons for recent additions to the schedule of prohibited exports, assumed that the hon. Member was referring to the changes made by the Export of Goods (Control) (Amendment No. 4) Order 1979 (SI 1979 No. 1437). On that assumption the answer needs clarification. Uranium hexafluoride has been under control for some years; the recent addition, as the order makes clear, was plant for the purification of uranium hexafluoride.
