There’s Guy Scott. He was acting president of Zambia in 2014-15 after the previous President died in office. Both of his parents were immigrants from the UK during the colonial period. But they were both pro-Independence and thus stayed after the colonial period ended.
Lol: “Referring to a 2012 meeting with former U.S. President George W. Bush (who sponsors various charity initiatives in Zambia), he said, "when they introduced me as Vice President, he thought they were kidding.”“
