Two out of five Supreme Court justices tasked with deciding the fate of the former Brazilian president, Jair Bolsonaro, have found the ex-leader guilty of plotting a coup.
But Bolsonaro will only be convicted if at least one more justice finds him guilty. The former president has denied all the charges against him.
The first justice to cast his vote, Alexandre de Moraes, said there was "no doubt" that there had been a coup attempt after Bolsonaro lost the 2022 presidential election to his left-wing rival, Luiz Inácio Lula da Silva.
The second justice, Flávio Dino, also found Bolsonaro guilty of all the five charges against him. The trial will continue on Wednesday.
When the session starts at 09:00 local (12:00GMT), all eyes will be on Justice Luiz Fux, whose turn it will be to cast his vote.
