MEXICO, July 4 (Xinhua) -- More than 3.5 million votes, from some 13,000 polling stations boxes, were ignored by the first count which gave conservative candidate Felipe Calderon the lead in Mexico's elections, a left-wing party told media on Tuesday.

    The left-wing Democratic Revolution Party (PRD), which put forward former Mexico city mayor, Andres Manuel Lopez Obrador for president in Sunday's elections, also called on Mexico's Federal Election Agency (IFE) to recount the vote exhaustively.

    Early counts give Calderon a slender 1.04 point lead over Obrador, results that Leonel Cota, the PRD's president; and Jesus Ortega, head of Obrador's campaign, have both rejected.

    "The PRD categorically rejects the legitimacy of the Preliminary Electoral Results Program (PREP)," Ortega told media on Tuesday.

    The PREP has excluded more than 13,000 polling stations, saying they showed "inconsistencies", Ortega said. He further alleged that participation data did not match the PREP results.

    According to the PRD, the PREP counted 98.45 percent of votes by the end of Monday and spoke of 38.4 million voters taking part. But the IFE had said that 58.9 percent of Mexico's registered voters had taken part: which should be 42.1 million voters. PREP statements indicated that more than 3.5 million votes had been excluded from the count, he said. Enditem
