Óscar Pérez-Oliva Fraga, who serves as the Deputy Prime Minister and is a grandnephew of both Raúl and the late dictator Fidel Castro, was spotted participating in a "volunteer work" event this past Sunday in El Vedado. He posted, "We shared the work day with Deputy Prime Minister Oscar and the Political Bureau member and FMC Secretary, comrade Teresa Amarelle." The New York Times AnalysisAn analysis by The New York Times on August 8 identified Pérez-Oliva Fraga as a potential replacement figure but noted he would "almost certainly be unacceptable" to Washington. Pérez-Oliva Fraga, son of Mirsa Fraga Castro and grandson of Ángela Castro—the elder sister of Fidel and Raúl—stands out as the most prominent heir of the Castro family. He was elevated to Deputy Prime Minister in October 2025, holding this position in addition to his role as Minister of Foreign Trade and Foreign Investment.
