Enrique Pena Nieto, the young face of Mexico’s oldest political party, looks to have been chosen to lead his country out of arguably the most turbulent period in its history since the Mexican Revolution.
Pena Nieto's PRI, which governed Mexico for 71 years until losing in 2000, has staged a comeback since the candidate was chosen.
The challenges facing any new president are enormous, including reducing poverty and combating the corruption and violence of organised crime.
But exit polls appear to show that there are enough Mexicans who believe Pena Nieto when he says his victory is not a regression to the past, but a transition to a new, less violent and more democratic era.
