Mexican President-elect Enrique Peña Nieto introduced on Tuesday the 46 members of the transition team that will work with the outgoing government of Felipe Calderon to prepare for the transfer of power.

Peña Nieto, of the Institutional Revolutionary Party, or PRI, named his erstwhile campaign manager, Luis Videgaray, to oversee the administrative aspects of the transition.

The policy element of the team will be led by Miguel Angel Osorio Chong, former governor of Hidalgo state.

"The electoral process has concluded and today I am working on the actions, programs and policies of the government of the republic that will take shape beginning Dec. 1," the president-elect told reporters at a Mexico City hotel.

"I am firmly committed, with complete devotion and complete resolution, for the next government of the republic to be truly capable of addressing the challenges that Mexico has today," Peña Nieto said.

His appearance before the media came days after he was declared Mexico's president-elect in the wake of the decision by the TEPJF electoral tribunal to reject a challenge to the validity of the July 1 election.

The transition team is drawn largely from the staff of the presidential campaign and people who worked with Peña Nieto during his 2005-2011 tenure as governor of the central state of Mexico.

But Peña Nieto did make one surprising appointment: naming former Mexico City Mayor Rosario Robles as deputy coordinator for social policy.

Robles was once leader of the leftist Party of the Democratic Revolution, or PRD.

It was PRD presidential hopeful Andres Manuel Lopez Obrador who brought the ultimately unsuccessful challenge to Peña Nieto's election victory.

Peña Nieto stressed that the members of the transition team will not necessarily be part of the new administration.

Scores of people demonstrated outside the hotel to denounce the PRI victory as the result of fraud.

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.

But the PRD-led Progressive Movement said the victory was tainted, alleging that the PRI used several front companies to purchase debit cards and then handed them out to millions of prospective voters to secure support for Peña Nieto.

The governing National Action Party, or PAN, whose candidate, Josefina Vazquez Mota, finished a distant third in the presidential election, joined with Lopez Obrador in demanding an investigation of the PRI's finances.

National Action, however, did not formally contest the election results.

The non-partisan Yo soy 132 student movement has held a series of protests and other events to block the "imposition" of Peña Nieto as president.

The final confirmation of the PRI's victory means the party will return to power in December after a 12-year absence.

The PRI, which governed Mexico from 1929 to 2000, lost the 2000 presidential election to the PAN and finished third in 2006.

During its 71-year reign, the PRI relied mainly on patronage and control of organized labor and the mass media, though it was not above resorting to outright vote-rigging and even violence. EFE
