MEXICO CITY -- The official count in Mexico's presidential election concluded on Friday with results showing that former ruling party candidate Enrique Pena Nieto won by a 6.6 percentage-point margin, almost exactly the same lead as a vote-night quick count gave him.

The final count by the country's electoral authority, which included a ballot-by-ballot recount at more than half of polling places, showed Pena Nieto getting 38.2 percent of votes in Sunday's election. Leftist Andres Manuel Lopez Obrador got 31.6 percent.

Lopez Obrador said he will file a formal legal challenge in electoral courts next week, based on the allegation that Pena Nieto's Institutional Revolutionary Party, or PRI, engaged in vote-buying that illegally tilted millions of votes. PRI officials deny the charge.

The final vote count must be certified in September by the Federal Electoral Tribunal. -- AP
