The party that ruled Mexico for seven decades returns to power with a president from a new generation.

The Institutional Revolutionary Party, or PRI, reclaims the presidency Saturday after 12 years out of power.

The Institutional Revolutionary Party reclaims the presidency after 12 years in what President-elect Enrique Pena Nieto calls a crowning moment.

The proposal to reform Mexico's dysfunctional, 1970s-era labor laws, loosen work rules and increase union democracy split Mexican political parties Tuesday.

Advocates say the reform, which will allow part-time work, hourly wages and outsourcing, will help Mexico create the million new jobs per year it needs.

The proposal threatens to create the first big political battle for President-elect Enrique Pena Nieto.

Andres Manuel Lopez Obrador said Friday that he is refusing to recognize the results of Mexico's presidential election.
