We are in São Paulo’s biggest polling station. The sun is shining, and lots of Brazilians have been coming here to cast their vote.

Many of them have stickers of Lula pinned on their shirts, hats and back pockets. But there are Bolsonaro supporters too.

“His government went through fundamental crises like the economy and the pandemic. It was unique. Bolsonaro didn’t get a chance to do everything he wanted to do, especially with the economy," Vicente, a doctor who voted for Bolsonaro, told us.

Franklin, who drives a taxi cab, brought his son along as he cast a ballot for Lula.

“There is so much polarisation," he said.

"But in the Lula era it wasn’t like this. I want to go back to that time. The economy was in better shape, our lives were better.

I hope Lula will calm down the souls - there is so much chaos right now."

It's now just after 17:00 (20:00 GMT) in Brazil’s capital, Brasilia, which means voting has officially come to an end.

However, anyone who joined the queue at polling stations by 17:00 and hasn't yet been able to vote will still be allowed to do so.

Unlike the last presidential elections, voting has come to a close at the same time across Brazil’s four different time zones.

Given voting is done electronically, we're expecting a result to be declared relatively quickly.

The two candidates didn't waste any time in voting earlier today.

Bolsonaro cast his vote just minutes after polling stations opened. He wore a T-shirt in the yellow and green of the Brazilian flag, colours which have become closely associated with his campaign.

Opinion polls suggest that the result could be very close but both candidates said they were confident of victory.

Bolsonaro told reporters that "God willing, we will be victorious in the afternoon, or rather, Brazil will be victorious in the afternoon".

Lula voted in São Bernardo do Campo in São Paulo state, saying that he was convinced that "the Brazilian people will vote for a project in which democracy will win".

Brazil's election chief, Alexandre de Moraes, has held a news conference after busses carrying voters were stopped by police at roadblocks.

Moraes said some voters had been delayed but that none had been prevented from voting.

Moraes, who is the head of the Superior Electoral Court (TSE), said the polls would close as planned at 17:00 local time (20:00GMT).

The head of the highway police had been summoned to the TSE earlier to explain why busses full of voters were being stopped.

Moraes says those involved in the stops could face further investigation.

Polls are due to close at 20:00 GMT.

Unlike in the UK general elections, there are no exit polls - but we do expect to have results coming in immediately.

However, as in the first round, it is likely to take several hours before it becomes clear who is in the lead.

In round one, we knew who had won by 00:30 GMT - so stay tuned as we bring you the latest updates.

Brazilian media are reporting that voting is generally proceeding smoothly and quickly.

During the first round four weeks ago, long queues formed and some polling stations stayed open beyond 17:00 local time (20:00GMT) in order to allow those already in the queue to cast their vote.

One voter in the north-eastern city of Fortaleza told the BBC it had been a question of minutes this time, while last time she'd had to wait for hours.

If all polling stations close as scheduled at 17:00 we may get a result fairly quickly.

In the first round, Lula won 48% against his far-right incumbent Jair Bolsonaro’s 43% - a much closer result than opinion polls had predicted.

Even though Lula won the round, he failed to reach the 50% of valid votes needed to win the election outright.

The election went into a run-off and in the four weeks since the first round, the two candidates have been trying to sway undecided voters and those who cast their ballots for one of the other eight candidates in the first round.

Today's winner will become Brazil's next president.
