Venezuela vote turnout was 32 percent by 6 pm: election board source

CARACAS (Reuters) - Participation in Venezuela's controversial presidential election on Sunday was at 32.3 percent by 6 p.m. as most polling stations began closing, according to an election board source. Turnout at Venezuela's last presidential election in 2015 was 80 percent, but the mainstream opposition called for a boycott of Sunday's vote, alleging it was rigged in favor of socialist leader Nicolas Maduro's re-election.
