As Mexico gears up for its presidential election, international observers are checking for signs of fraud.
Hundreds of monitors are deployed across the country, which hopes to prove that practices of vote-rigging are in the past.
Electoral officials met with leftist candidate Andres Manuel Lopez Obrador's party after he raised concerns of vote-buying.
Obrador's loss to President Felipe Calderon in 2006 sparked massive protests amid fraud allegations.
(SOUNDBITE) (Portuguese) BRAZILIAN ELECTION OBSERVER, PAULO FERREIRA, SAYING:
"Mexico has surprised me that for an evolved and advanced country with a common electoral process the voting mechanics are still tainted following decades of an insecure process from the point of view of confidence and transparency."
The presence of nearly 700 observers from 69 countries make this Mexico's most closely monitored election.
But voters are still wary - a local polling organisation survey showed only 30 percent had high confidence in the country's electoral authorities.
