Polls have opened in Brazil to vote for the country's next president.

Brazilians are choosing between Brazil's current left-wing President Luiz Inácio Lula da Silva and the right-wing Senator Flávio Bolsonaro.

Bolsonaro, the son of imprisoned former president Jair Bolsonaro, beat Lula in the first round of voting on 4 October by a narrow margin.

Americas correspondent Ione Wells reports from Rio de Janeiro as voters choose between two very different candidates.
