Enrique Pena Nieto took the oath of office as Mexico's new president on Saturday, promising a list of specific reforms that are part old-party populist handouts to the poor and new assaults on the entrenched systems and sacred cows that have hampered the country's development.
Tens of thousands of people marched in Mexico's capital on Saturday to protest Enrique Pena Nieto's apparent win in the country's presidential election, accusing his long ruling party of buying votes.
The official count in Mexico's presidential election concluded on Friday with results showing that former ruling party candidate Enrique Pena Nieto won by a 6.6 percentage-point margin, almost exactly the same lead as a vote-night quick count gave him.
Mexican electoral authorities said Wednesday they will recount more than half the ballot boxes used in the weekend's presidential elections after finding inconsistencies in the vote tallies.
Thousands of people rushed to stores Tuesday to redeem pre-paid gift cards they said were given to them previously by the party that won Mexico's presidency, inflaming accusations that the weekend election was marred by widespread vote-buying.
The party that ruled Mexico with an iron grip for most of the last century has sailed back into power, promising a government that will be modern, responsible and open to criticism.
Presidential candidate Enrique Pena Nieto led Mexico's elections with about 40 per cent of the vote, exit polls showed Sunday, signalling a return of his long-ruling party to power after a 12-year hiatus.
