Venezuela’s presidential candidates have given their final speeches ahead of this weekend’s election to choose a replacement for President Hugo Chávez, who died of cancer last month. Hundreds of thousands rallied in the capital Caracas to support Nicolás Maduro, a former bus driver and Chávez’s chosen successor. Maduro is leading in the polls ahead of challenger Henríque Capriles, who lost to Hugo Chávez in last year’s election.
