Brazilians vote in presidential election runoff pitting leftist Lula against far-right Bolsonaro

• Brazilians are voting on Sunday in a highly unpredictable presidential runoff, with leftist president Luiz Inácio Lula da Silva attempting a comeback against far-right senator Flávio Bolsonaro, who won the first round. • The first-round gap was the narrowest ever recorded at less than 2% of the vote, and record-high abstention disproportionately affects Lula’s voters. • Bolsonaro, the eldest son of jailed ex-president Jair Bolsonaro, has promised to pardon his father if elected and has vowed to "change the constitution and re-democratise this country".
