In the first round of Brazilian elections, on October 2 , the presidential candidate, former leftist President Luiz Inacio Lula da Silva received 48% of the vote against 43% for Jair Bolsonaro. The result of the latter came out much higher than the opinion polls predicted, which gave him some momentum during the second campaign.

During more than two hours on "TV Globo", the most watched channel in the country, the two candidates hurled insults and accusations of lying, instead of presenting their concrete projects for the next four years.

Brazilians reached the end of a heated presidential campaign on Saturday, a day after the last televised debate between Lula and Jair Bolsonaro, who exchanged insults before Sunday's second round.

Right-wing president Jair Bolsonaro, 67, said, "Lula, stop lying, go home," according to AFP.

Former leftist President Luiz Inacio Lula da Silva, who celebrated his 77th birthday on Thursday, did not remain silent, saying: "this man is the biggest liar in the history of Brazil" he is a "psychopath".

Bolsonaro then asked his opponent, "are you taking Viagra?""Referring to the controversy surrounding the purchase of 35,000 Viagra pills for the military.

Lula attacked his opponent on his international policy and said: "under your government, Brazil has become a pariah. No one wants to receive you and no one comes here," Bolsonaro replied sarcastically "he thinks himself the father of the poor", before calling him a "thief".

Lula da Silva, a former president who is leading in opinion polls, was jailed for 18 months for corruption in 2018 and 2019 before the sentence was overturned.

Friday's debate was the culmination of a dirty campaign in which a torrent of misinformation was spread on social media.

"It was an argument that did not come up with anything that could change the data,"Political Writer Ottavio Guedes said via GloboNews after the debate.

Lula slightly increased his lead in the latest poll conducted by the Datafolha Datafolha institute and published on Thursday (from 4 to 6 points), receiving 53% of voting intentions, against 47% for the right-wing president
