Mexico's conservative presidential candidate, Felipe Calderon, snatched a razor-thin election victory today, but his leftist rival vowed to fight the result in the courts and on the streets.
The Harvard-educated Calderon had an insurmountable lead with nearly 36% of the vote and only a few dozen polling stations pending.
Mexico's Federal Electoral Institute said it would declare the winner on the basis of these overall results.
Andres Manuel Lopez Obrador, a combative left-wing former Mexico City mayor, was 0.57 points behind Calderon and angrily claimed the vote was plagued with irregularities.
