Lula widened his first-round lead, with 42% of the votes against 37% for the eldest son of former President Jair Bolsonaro, according to a BTG/Nexus poll cited by Reuters.

In a potential runoff, Lula would receive 46% against 44% for Bolsonaro — a tie within the margin of error. The previous survey by the same institute had Lula at 40% and Bolsonaro at 37% in the first round.
