Brazilian President Luiz Inacio Lula da Silva and right-wing Senator Flavio Bolsonaro have wrapped up their election campaigns, each voicing confidence in victory ahead of Sunday’s tightly contested first-round presidential vote.

Lula, 80, closed his re-election bid on Saturday with a march through Sao Paulo, Brazil’s economic powerhouse, drawing what his campaign called a record crowd for a closing rally.

“Tomorrow, we’re going to win the elections in the first round,” he told supporters, describing Sunday’s vote as a choice between “democracy and barbarism” and promising to “defeat the far right”.

He has also framed the election as a test of Brazil’s sovereignty, warning against “meddling” by Washington.
