Tony da Costa Fernandes (born c. 1943) served as the Foreign Minister of UNITA, a rebel group in Angola. In the 1990s Fernandes and UNITA Interior Minister General Miguel N'Zau Puna allegedly uncovered the fact that UNITA leader Jonas Savimbi ordered the assassinations of both Wilson dos Santos, Angola's representative to Portugal, and Tito Chingunji, one of Costa Fernandes' predecessors. Dos Santos and Chingunji's deaths and the defections of Fernandes and Puna weakened the U.S.-UNITA relationship and seriously harmed Savimbi's international reputation.
