Andres Manuel Lopez Obrador alleges that Enrique Pena Nieto bought votes in the recent election in Mexico. These accusations are likely to lead to a legal challenge of the election's outcome.
The official count of Mexico's presidential election confirmed the victory of Enrique Pena Nieto, the candidate seeking to return the former autocratic ruling party to power after a 12-year hiatus, the country's electoral authority reported Thursday night in a major step toward the resolution of the contested vote.
With just over 99 percent of the ballot boxes counted as of 9 p.m., more than half of them double-checked due to the possibility of fraud, Pena Nieto had more than 38 percent of the vote. In second place was leftist Andres Manuel Lopez Obrador with more than 31 percent. That gave Pena Nieto a lead of more than 3.3 million votes.
Lopez Obrador alleges Pena Nieto's Institutional Revolutionary Party, or PRI, engaged in vote-buying that illegally tilted millions of votes toward the party that controlled virtually all Mexico's institutions until it lost the presidency in 2000. Lopez Obrador has not specified exactly how many votes he believes were bought.

The ruling-party candidate who came third in Mexico's presidential elections also said earlier in the day that campaign spending violations had marred the vote, although she stopped short of challenging the legitimacy of the outcome.
The complaint by National Action Party candidate Josefina Vazquez Mota nonetheless added weight to growing accusations that Pena Nieto benefited from vote-buying schemes.
