MEXICO CITY — Mexican electoral authorities said Wednesday they will recount more than half the ballot boxes used in the weekend's presidential elections after finding inconsistencies in the vote tallies.
Of the 143,000 ballot boxes used during Sunday's vote, 78,012 will be opened and the votes recounted, said Edmundo Jacobo, executive secretary of Mexico's Federal Electoral Institute.
Jacobo said the recount could be finished by Thursday.
Mexico's electoral law states that the votes should be recounted if there are inconsistencies in the final tally reports, when the result shows a difference of one percentage point or less between the first and second place finishers or if all the votes in a ballot box are in favor of the same candidate.
With 99 percent of the vote tallied in the preliminary count, Enrique Pena Nieto of the Institutional Revolutionary Party, or PRI, led with 38 percent of the vote. Andres Manuel Lopez Obrador of the Democratic Revolution Party had 32 percent.
Authorities also will recount 61 percent of the ballot boxes in the vote for the Senate and 60 percent in the vote for the lower house of Congress, Jacobo said.
Lopez Obrador has refused to accept the preliminary vote tallies, saying the election campaign was marred by overspending, vote-buying and favorable treatment of Pena Nieto by Mexico's semi-monopolized television industry.
The leftist candidate said Tuesday that his team had detected irregularities at 113,855 polling places, and called for a total recount.
Feeding suspicion of large-scale vote-buying were scenes of thousands of people rushing to grocery stores this week to redeem pre-paid gift cards they said the PRI had given them ahead of the vote. Several told reporters they had been told to turn in a photocopy of their voter ID card in order to get the gift cards.
Under Mexican election law, giving voters gifts is not a crime unless the gift is conditioned on a certain vote or is meant to influence a vote. However, the cost of such gifts must be reported, and cannot exceed campaign spending limits. Violations are usually punished with fines, but generally aren't considered grounds for annulling an election.
Shoppers nearly stripped some shelves at a Soriana store in the poor district of Iztapalapa and officials in Mexico City, which is governed by Democratic Revolution, ordered at least one branch of the chain closed for alleged violation of safety codes.
Both the PRI and the supermarket company denied any irregularities.
PRI spokesman Eduardo Sanchez said that "Neither the PRI's executive committee, nor Enrique Pena Nieto's campaign has contracted any service from the Soriana grocery store chain.
Asked if some other local or congressional PRI candidate could have done it on behalf of Pena Nieto, he said "I don't know."
Humberto Fayad, a spokesman for the Soriana chain, denied the company had sold huge amounts of gift cards to the PRI.
"There is no agreement between the PRI and Soriana, or Soriana and any other political party. Soriana is a non-political company," Fayad said.
The PRI, too, accused rivals in many parts of the country of handing out groceries or using government programs to influence voters.Comment on this story
The governing National Action Party accused Pena Nieto's campaign of acquiring about 9,500 prepaid gift cards worth nearly $5.2 million (71 million pesos) to give away for votes. Authorities said a business had bought that number of cards, but that they had found no direct evidence of vote-buying. That investigation continues.
On Tuesday, Alfredo Figueroa, a council member of the Electoral Institute, said authorities were investigating complaints about the Soriana gift cards. Members of the institute have said they were aware of attempts to engage in vote buying.
