After exit polls suggested that leftist Andres Manuel Lopez Obrador will win Mexico's presidential election by a large margin, other candidates conceded defeat.
Jose Antonio Meade, the candidate of the ruling Institutional Revolutionary Party (PRI), said Lopez Obrador had "won the majority" in Sunday's election, adding: "I wish Andres Manuel the greatest of success."
Another candidate Ricardo Anaya said he had called Lopez Obrador to concede.
"I recognize his victory and express my congratulations, and I wish him the greatest of success, for the good of Mexico," Anaya told supporters.
