Is the Prime Minister aware that the whole House, I believe, will welcome that announcement? Could he say whether the Governments of Nyasaland and Northern Rhodesia, which will soon become independent, will be invited to send representatives to the Prime Ministers' conference? Could he say whether the increasingly unrepresentative Government of Southern Rhodesia will be invited to send a representative? Could he confirm that Southern Rhodesia will be one of the subjects discussed and, if so, whether the crisis in British Guiana will also be on the agenda?
