Brazil heads to 25 October runoff as Flávio Bolsonaro leads Lula

Flávio Bolsonaro led Brazil's 4 October first round with 47.3% to incumbent Luiz Inácio Lula da Silva's 44.8%, forcing a 25 October runoff. Bolsonaro, 45-year-old son of jailed ex-president Jair Bolsonaro, faces Lula, seeking a fourth term. The narrow gap leaves three weeks of coalition-building to decide Brazil's presidency.
