Brazil election: Lula’s challenge hangs in balance amid voter suppression claims

Tens of millions of progressives turn out in hopes of unseating Jair Bolsonaro from presidency after bitterly fought campaign

The future of one of the world's largest democracies and the Amazon rainforest was on a knife-edge as Brazil held its most important election in decades and its far-right president, Jair Bolsonaro, battled to cling to power amid claims that security forces were engaged in a pro-Bolsonaro voter suppression campaign.

Polls on the eve of the election had showed Bolsonaro trailing his leftist rival, the former president Luiz Inacio Lula da Silva, by a margin of four to eight percentage points, although first-round polls had underestimated support for the incumbent. Lula won the recent first round by about 6mvotes but fell just short of the overall majority that would have guaranteed him an outright win.
