On Sunday, it was clear that left-wing leader Lula da Silva won the Brazilian presidential election with 50.9 percent of the vote against incumbent President Jair Bolsonaro's 49.1.

Since then, there has been silence from Bolsonaro, and on Tuesday - a day and a half after the election results were announced - he still had not spoken publicly and admitted defeat.

Does not dispute the result

Now Bolsonaro's communications minister, Fabio Faria, tells the Reuters news agency that the president will not dispute the result.

He will give a speech to the nation later on Tuesday, before which he will meet with judges of Brazil's Supreme Court, Faria said.

Reuters also reports that several of Bolsonaro's political allies, including his chief of staff, have already begun to establish contact with da Silva's camp to discuss handing over power.

Bolsonaro's silence has raised fears that the president, who has repeatedly warned of the risk of electoral fraud, would not recognize da Silva as the winner.

Protests around Brazil

Since it became clear that da Silva would take power, thousands of supporters of Bolsonaro in at least 11 states have blocked hundreds of highways in protest of the election results.

Among other things, they have blocked important transportation routes for grain and a major road connecting Brazil's two largest cities, Rio de Janerio and Sao Paolo.

On Monday, protesters blocked the main road to Sao Paolo airport, resulting in the cancellation of 25 flights.

On Tuesday morning, however, the road could be reopened.

Brazil's Supreme Court on Tuesday ordered police to immediately dissolve the roadblocks, Reuters reports.
