CARACAS/BRASILIA, Aug 1 (Reuters) - The presidents of Brazil, Mexico and Colombia called for Venezuela to release detailed voting tallies on Thursday, amid a dispute over presidential election results that has sparked protests.

Venezuela’s electoral council proclaimed Maduro, who has been in power since 2013, the winner of the July 28 election with 51% of the vote.

But the country’s opposition says its tally of about 90% of the votes shows its candidate Edmundo Gonzalez received more than double the support of the incumbent president, in line with independent polling conducted before the contest.
