How Lula won

Luiz Inácio Lula da Silva sealed a fourth presidential term in the second round of Brazil's presidential election, defeating the far-right rival Flávio Bolsonaro who had beaten him in the first round. The brazil presidential election result ended at 51.79% for Lula and 48.21% for Bolsonaro.

The vote carried several unusual features readers may want to ask about:

• •It was the first time in Brazilian electoral history that a first-round verdict had been overturned.
• •A supreme court judge extended polling time by two hours before the result was delivered.
• •Lula's camp accused their opponents of sabotaging public transport in an attempt to keep their voters from the polls.

Flávio Bolsonaro rejects the result

Flávio Bolsonaro has refused to accept the result, just as his father Jair Bolsonaro did four years before. He is the son of the former president, who is serving a 27-year jail term for his part in an attempted coup after the last presidential election.

Flávio Bolsonaro called Lula's victory "sacanagem", a Portuguese word that roughly translates as "bullshit".

What a fourth term holds

The lula victory brazil election makes him the country's longest-serving leader, and he turns 81. He will govern with a hostile Congress packed full of Bolsonaro allies, and an economy facing soaring debt and entrenched structural problems.

Guardian columnist Jordana Timerman wrote: "Lula's victory shows that the rightward shift is neither inevitable nor irreversible".
