After losing the first round of Brazil's presidential election to far right rival Flavio Bolsonaro, incumbent Luiz Inacio Lula da Silva, better known simply as Lula, pulled off the most stunning political fightback in modern Brazilian history by winning the second, in so doing securing a fourth presidential term. It will see him become the country's longest-serving leader.

The result - 51.79% to Lula, 48.21% to Bolsonaro - was delivered after a supreme court judge had extended polling time by two hours, and after Lula's camp accused their opponents of sabotaging public transport in an attempt to keep their voters from the polls. It was the first time in Brazilian electoral history that a first-round verdict had been overturned.
