Mexico’s old guard in dramatic return to power

Mexico’s old rulers have claimed victory in a presidential election, ending 12 years in opposition after a campaign dominated by a sputtering economy and rampant drug violence.

After pledging to restore order and ramp up economic growth, Enrique Pena Nieto of the Institutional Revolutionary Party (PRI) had a clear lead over his rivals in exit polls and a quick count conducted by electoral authorities.

Although his main rival said it was too early to concede defeat, the 45-year-old Pena Nieto delivered a late-night victory speech to cheering supporters, and a senior electoral official said the PRI candidate’s lead was irreversible.
