Brazil heads to the polls for high-stakes election between Lula and Flavio Bolsonaro

Brazilians began casting their votes on Sunday in a closely watch presidential election pitting incumbent President Luiz Inacio Lula da Silva against right-wing Senator Flavio Bolsonaro, son of former president Jair Bolsonaro. Nearly 160 million voters will also pick lawmakers, senators and governors in an election that will determine whether Latin America's biggest nation follows a regional swing to the right championed by US President Donald Trump.
