Mariana Haydee Triaca, the sister of Labour Minister Jorge Triaca, is the new head of Banco Nación, a presidential decree published yesterday revealed.
The decree bears the signatures of President Mauricio Macri and his Finance Minister Luis Caputo.
There is a history of controversy surrounding the direction of the bank.
In mid 2015, former Defence minister Agustín Rossi’s daughter, 26-year-old Delfina, was appointed to the same role. An injunction lodged against her appointment by a member of Macri’s own PRO party was later rejected by the courts.
