AHC: Have the Federation of Rhodesia and Nyasaland survive and have it become independent

By becoming independent, I mean in the process of decolonization where colonies, self-governing or not eventually become fully independent to take care of themselves.
 
This is borderline ASB, but, Garfield Todd manages to hold on as Premier of Southern Rhodesia and keeps leadership of the UFP (maybe he appoints Holderness and more of the liberals to his cabinet so that the coup doesn't happen). He builds a coalition of liberal Europeans and Africans and manages to expand the franchise in Southern Rhodesia such that the UFP is able to maintain its lead over the Dominion Party (difficult, but not impossible). Africans in Nyasaland and Northern Rhodesia are then convinced that "partnership" is possible and do not push for the dissolution of the Federation. Welensky is then forced to expand the franchise at a Federal level and the UFP is rewarded. Todd moves to Federal politics and takes over leadership of the federal UFP. By the 1970s, the Federation of Rhodesia and Nyasaland is similar to modern day South Africa.
