COTONOU - Three people plotted to kill Benin’s President Thomas Boni Yayi by substituting poison for his medicine, prosecutors say. The president’s doctor, one of his nieces and an ex-minister of commerce have been charged with conspiracy and attempted murder, officials said. According on to BBC, prosecutors said the president’s niece and his doctor were offered 1bn CFA francs (£1.2m; $2m) to poison him. The three have been remanded in custody, officials say. Prosecutors yesterday named them as Dr Ibrahim Mama Cisse, the president’s niece Zouberath Kora-Seke and former minister of commerce Moudjaidou Soumanou. Authorities said they also intended to issue an arrest warrant for businessman Patrice Talon, an ex ally of Yayi.
