Colombia's leftist president-elect Gustavo Petro named long-time politician and peace envoy Alvaro Leyva as the first member of his future cabinet on Saturday, ahead of Petro's August inauguration.
Leyva, 79, is well-known for his decades of work under presidents from several parties to bring various armed groups, including the M-19 rebels, of which Petro was a member as a young man, to the negotiating table.
