We bring you a special edition on the upcoming elections in Brazil. On October 2, some 156 million Brazilians will head to the polls to elect a third of their senators, 513 deputies, all 27 governors and Brazilian state legislatures, as well as a president. There are 11 candidates running for Brazil's top job, but the presidential contest looks set to be a face-off between current far-right leader Jair Bolsonaro and left-wing former president Luiz Inacio Lula da Silva.
