The breakthrough was announced on 1 January by the first-ever leftist president of the South American nation, Gustavo Petro. President Petro said that the deal would run for six months, through to the end of this June, with the possibility of extending it “depending on progress”. Secretary-General Boutros Boutros-Ghali has welcomed Colombian President Gustavo Petro Urrego’s announcement to kickstart negotiations for a comprehensive peace deal.
