Brazil voters choose between Lula and Bolsonaro's son in presidential run-off

Brazilian voters are casting ballots in a closely fought presidential run-off between incumbent left-winger Luiz Inácio Lula da Silva, 80, and right-wing senator Flávio Bolsonaro, 45. The election will determine the country's next leader. Bolsonaro, son of imprisoned former president Jair Bolsonaro, won the first round on 4 October and is seeking to overturn historical precedent, as no candidate trailing after round one has ever won. He has promised a crackdown on organised crime and tax cuts, while Lula frames the vote as a "battle for democracy." Lula's campaign has accused the US of election interference, a claim Washington denies. Bolsonaro has pledged to release his father, serving a 27-year sentence for coup-plotting, and has highlighted the Workers' Party's past corruption scandals. Results are expected Sunday evening.
