Brazil's presidential election will proceed to a runoff after neither incumbent President Lula nor challenger Flávio Bolsonaro secured the required majority in the first round. Lula, aiming for a comeback, and Bolsonaro, the son of former President Jair Bolsonaro, will compete for the presidency on October 25. Both candidates face significant challenges as they seek to attract moderate voters and navigate their respective controversies ahead of the decisive vote.
