Venezuelans go to polls in Chavez's toughest election

President faces major challenge from business-friendly Capriles

Venezuelans voted on Sunday in the toughest election President Hugo Chavez has faced in almost 14 years in power after fresh-faced rival Henrique Capriles electrified the country's opposition.

Chavez, 58, retains a loyal following among the country's poor, who have propelled him to easy victories in past elections, but 40-year-old Capriles has narrowed the gap in opinion polls after an energetic door-to-door national campaign.
