Experts say strength of evangelical church and perception that Lula is too old also helped propel Jair Bolsonaro’s son to first-round election win

On Sunday night, as the scale of the far-right triumph in Brazil sank in, an adapted football chant rang out in one of Rio’s most leftwing areas.

“Let’s turn this around, Lu-laaaaa! Let’s turn this around, Lu-laaaaa! Let’s turn this around, Lu-laaaaa!” crestfallen progressives bellowed while drowning their sorrows after witnessing an excruciating election setback for their leader, Luiz Inácio Lula da Silva.

The polls have closed in the first round of Brazil’s highly polarised and high-stakes presidential election that could change not only the direction of Latin America’s largest country but that of the entire region.

The election pits the leftwing president, Luiz Inácio Lula da Silva, who is seeking a fourth non-consecutive term, against the far-right senator Flávio Bolsonaro, an ally of Donald Trump and the son of the former president Jair Bolsonaro, who is serving a 27-year sentence for attempting a coup after his failed 2022 re-election attempt.

Shortly after his controversial speech to the United Nations general assembly in September, Donald Trump gathered a dozen like-minded Latin American leaders and boasted that rightwing candidates had won all seven presidential elections held in the region since he began his second term.

“Everybody I’ve endorsed has won,” the US president said in New York to most of the leaders of the Shield of the Americas, an anti-drug cartel coalition of 15 countries governed by the right or far right.

The politically charged dispute exploded into public view on Tuesday as judges traded insults and accusations during a heated supreme court hearing that was livestreamed into millions of Brazilian homes.

The far-right populist Jair Bolsonaro was in his final days as Brazil’s president when, six weeks after losing the election and still refusing to recognise the result, he summoned the heads of the armed forces to a meeting.

The defence minister, Gen Paulo Sérgio Nogueira de Oliveira, took out a document from a plastic folder and handed copies to the commanders of the navy, army and air force.

Revelation seen as serious blow to candidacy of Flávio Bolsonaro, Brazil’s leading rightwing presidential hopeful

Flávio Bolsonaro, Brazil’s leading rightwing presidential hopeful, has been caught on tape asking a banker accused of corruption for $26.8m (£20m) to fund a film about his father, the former president Jair Bolsonaro.

The leaked voice memos and text messages were published on Wednesday by the Intercept Brasil, and later acknowledged by Flávio Bolsonaro, a far-right senator who is tied in polls with President Luiz Inácio Lula da Silva ahead of October’s election.
