Gustavo Francisco Petro Urrego is a politician, economist, former presidential candidate, and member of the national Senate. He previously served as mayor of Bogota. Runner-up in the 2018 Colombian presidential elections , Petro--together with his vice-presidential partner, Angela Maria Robledo--is currently the leader of the opposition to the administration of the current president, Ivan Duque, considered by most to be a mere stand-in for former president Alvaro Uribe Velez. Senator Petro, together with Congresswoman Robledo, is the leader of Colombia Humana, a large political movement that obtained more than eight million votes in the 2018 elections but which has been denied legal status as a political party by the current administration making it currently ineligible for formal electoral participation, all too similar to what detractors of Venezuela's current government are accused of doing.
