Having regard to the requests for a future debate on Rhodesia, and appreciating what the right hon. Gentleman has said, may I ask whether the Prime Minister did not say yesterday that he supposed, or expected, or hoped that there will be some finality in the exchanges with Salisbury by the end of this week? Therefore, in view of the undertakings that have been given, are we to suppose that no further action in the matter will be taken by the Government in anticipation of the debate? That is the problem that is worrying many of us on both sides. Could the right hon. Gentleman clarify the position?
