I am grateful for the right hon. Gentleman's opening remarks. I can confirm that although we have not yet worked out a detailed itinerary, Mr. Richard will be visiting not only the five front-line African States but South Africa and Rhodesia. I prefer not to go into more detail now on the second question. The question of the extent of the British presence and involvement is an extremely difficult matter. I confine myself to saying that whatever it is, it will stop short of sending British troops.
