Career
He came to Britain where he was a prominent academic in the Politics department at the University of New York Leftwich was best known among South African students of his generation for turning state evidence against his collaborators in a 1964 anti-apartheid bomb plot with the African Resistance Movement (ARM). He and a small group of fellow students blew up a Cape Town suburban railway signal cable after which he was detained on 4 July 1964.
While some of those arrested maintained bitter resentment against Leftwich, others made efforts to reconcile with him.
Stephanie Kemp, who spent time in jail for her involvement in the bombing, stated on her Facebook page that she had "gone through a painful journey of reconciliation with him over 12 or more years. He was the same person, although he could never forget his fall almost 50 years ago.
In the United Kingdom, Leftwich worked on the politics of development, and was one of the foremost thinkers in the now increasingly popular political settlements approach to development, which sees deals between leading groups as crucial for effective development. He was research director of the Developmental Leadership Programme, which looks into the key roles played by leaders, elites, and coalitions in economic development.
He noted that "development has also managed to come around in states that are run by corrupt elites - just as long as these elites are relatively less corrupt and as long as they are determined in the cause of development, independent of the special interest groups.
