Leftist Colombia presidential candidate Gustavo Petro's promises to halt new oil projects and redistribute pension funds could put the country's economic stability at risk, investors say, though doubts remain about his ability to implement them.
Petro, a senator and former M-19 guerrilla rebel, has tallied up to 37% of intended votes in recent polls, putting him 10 points ahead of the center-right Federico Gutierrez but unlikely to win in a first round.
