text: the spirit of the Charter of the United Nations, and the view of numerous organizations and bodies throughout the world which have condemned the unilateral declaration of independence by the rebels, we call for the adoption by Britain of measures which will facilitate realization by the people of Zimbabwe of their independence and right to self-determination. Indeed, that has been the untainted message of the General Assembly and to some extent-and to some extent only, as I shall show later-of this Council since 1965. 8. The Council has patently been pained by the realization that the measures it has taken since 1965 have so far been 1 ineffective. It is for that reason that resolution 320 (1972), and in particular its paragraphs 4 and 5, requested the Security Council Committee established in pursuance of resolution 253 (1968) to undertake, as a matter of urgency, consideration of the type of action which would be taken in view of the open and persistent refusal of South Africa and Portugal to implement sanctions against the illegal rCgime and to submit a report inter alia for extending the scope and improving the effectiveness of sanctions against Southern Rhodesia. 9. I do not find it necessary to repeat that the Com- mittee’s report to the Council contained in document S/l0920 and Corr.1 hardly meets the mandate of the Council. The reason is quite clear. It is that in spite of modest African proposals supported and significantly im- proved upon by the delegations of China and the USSR, to which my delegation is grateful, the United Kingdom and the United States would not let down Southern Rhodesia, South Africa and Portugal by enabling the Committee, and subsequently the Council, to discharge its mandate by adopting measures likely to bring about the fall of the Southern Rhodesian illegal rigime.
