Speaking at the press conference in Argentina's Buenos Aires, Morales said: "What I want are free, sound and transparent elections. I am not going to be a candidate but I have a right to be involved in politics. As long as I am alive, I will remain politically active in service to, and as a sacrifice for, the poorest."

After weeks of opposition protests against his re-election for a fourth term, Morales resigned and first flew to Mexico and then arrived in Argentina, which both offered him refuge.

In order to eliminate Morales from the race, lawmakers passed a bill that bars candidates who have already served two presidential terms.
