Right-wing candidate Flavio Bolsonaro attracts foreign support, but struggles in polls ahead of matchup with President Lula.

Flavio Bolsonaro has inaugurated the official beginning of his Brazilian presidential campaign, touting support from right-wing figures such as Argentinian President Javier Milei and Israeli Prime Minister Benjamin Netanyahu.

Bolsonaro, son of former president Jair Bolsonaro and long considered the presumptive candidate of Brazil’s political right, launched his formal bid challenging President Luiz Inacio Lula da Silva on Saturday.

“This is more than a party convention,” Bolsonaro said in remarks to his father’s Liberal Party.

“This is the beginning of the toughest battles of our life. A fight between good and evil.”

Recent polls have shown Bolsonaro trailing the left-wing Lula, as his bid for the presidency struggles to right itself after a number of setbacks and scandals.

While Saturday’s event included endorsement remarks from right-wing heavyweights such as Milei and Netanyahu, few prominent Brazilian politicians were in attendance.

Centre-right parties have largely kept their distance, and Flavio’s father – currently serving a 27-year prison sentence for a coup attempt following his loss to Lula in 2022 – was present at the convention only in the form of a video made with AI.

Milei delivered ‌a fiery speech criticising Lula and declaring that Bolsonaro can “save” Brazil from socialism.

The Argentinian president flew to Brazil the night before the event and met on Saturday with Sao Paulo Governor Tarcisio de Freitas.

“We will continue offering our testimony everywhere against the lies of socialism,” Milei said.

Netanyahu offered support via a short video message.

“Flavio, my friend, I want to congratulate you on the official launching of your campaign,” Netanyahu said in the recording, according to the Brazilian outlet Metropoles. “You’re a great champion of Brazil, you’re a great champion of the friendship between our peoples.”

Lula’s Workers Party is set to hold its own convention on August 2, confirming the 80-year-old president’s re-election bid.

Bolsonaro and his allies have also suffered from criticisms that they have tried to use their ties to the administration of US President Donald Trump to boost his campaign, inviting US intervention in a variety of issues that many Brazilians see as a form of foreign meddling.

Like his father, Flavio has also raised alarm by repeating false claims about the reliability of Brazil’s election infrastructure, seen as a pretext for possible efforts to deny the legitimacy of the voting process in the event of a loss to Lula.

The AFP news agency reported on Saturday that Brazil had denied visas to a pair of Trump administration officials who sought to meet with the country’s election authorities to discuss “freedom of expression related to the elections”.
