From Wikipedia

'Fraser opposed white minority rule in Rhodesia. During the 1979 Commonwealth Conference, Fraser, together with his Nigerian counterpart, convinced newly-elected British PM Margaret Thatcher to withhold recognition of the internal settlement Zimbabwe Rhodesia government (Thatcher had earlier promised to recognise it). Subsequently, the Lancaster House talks were held and Robert Mugabe was elected leader of an independent Zimbabwe in 1980. A former deputy secretary of the Department of Foreign Affairs and Trade has stated that Fraser was 'the principal architect' in the instalation of Robert Mugabe. Tanzanian president Julius Nyerere said he considered Fraser's role "crucial in many parts", and Zambian president Kenneth Kaunda called it "vital". [6]'
