Venezuela’s opposition leader has vowed to fight late Hugo Chavez’s preferred successor for the presidency next month and the pair quickly locked horns in an angry war of words. Henrique Capriles, a 40-year-old state governor, will face election favorite and acting President Nicolas Maduro. The pair were to register their candidacies for the April 14 vote on Monday. The election will decide whether Chavez’s self-styled socialist and nationalist revolution will live on in the country with the world’s largest proven oil reserves. “I am going to fight,” Capriles said at a news conference. “Nicolas, I am not going to give you a free pass. You will have to beat me with votes.”
