Party of the Democratic Revolution, or PRD, chairman Jesus Zambrano has opened the door for a possible meeting with President-elect Enrique Peña Nieto, whose victory in Mexico's July 1 presidential election has not been recognized by the left.

A meeting has not yet been confirmed with Peña Nieto, of the Institutional Revolutionary Party, or PRI, and no date or place have been set, Zambrano told reporters.

It had been reported that a meeting might take place after the president-elect returned from his recent tour of Europe, but it did not.

A meeting between PRD leaders and the president-elect would not be a betrayal of leftist presidential candidate Andres Manuel Lopez Obrador, Zambrano said.

Party leaders "would be confirming the conviction of strengthening the weight of the institution and the mutual respect between the branches (of government), and leaving the issues clear," the PRD chairman said.

The parties that made up the leftist Progressive Movement, whose candidate was Lopez Obrador, refused to recognize Peña Nieto's victory, alleging that it was made possible by a massive vote-buying operation and tainted money.

Mexico's top electoral court certified Peña Nieto's win.

Peña Nieto won the election with 38.21 percent of the vote, while Lopez Obrador took second place with 31.59 percent, according to the final official results released by the Federal Electoral Institute. EFE
