The main question is that the attackers have come from Angola. Then the question is what is the involvement of the Angolan Government. As for Cuban involvement in Africa generally, and Cuban involvement in Angola in particular, the view of the British Government is clear and is well known. I ask the hon. Gentleman to look at the issue in its historic perspective. There is no doubt that there is a danger of adventurism of the kind we have seen by the Soviet Union and by Cuba there. But at root there is a complex dispute over Katanga which goes back deep in history, We need to stand back and to consider it in that context, as well as in that of our genuine concern for other dangers.
