Background on Conviction
The former president was convicted of leading a conspiracy aimed at maintaining his control after he lost the national vote to his left-wing rival, Luiz Inácio Lula da Silva.
Supreme Court justices said that he was aware of a plot which encompassed plans to murder his opponent and his vice-presidential running mate, Geraldo Alckmin, and to detain and kill Justice Moraes - the top judicial official who has been overseeing Bolsonaro's trial.
The plot was stopped because it couldn't obtain the support of the military leaders. The current president was inaugurated without problem on the first day of 2023.
But a following week, on 8 January, thousands of his backers stormed and vandalised government buildings in the federal district, Brazil's capital.

The justices found that the rioters had been encouraged by Bolsonaro whose strategy, they said, was for the Brazilian military to take action, restore order and bring him back to power.
At the time, his attorneys called the decades-long sentence "absurdly excessive.
He was also prohibited from running for public office until 2060 - a decade minus two years after the end of his sentence.
The former president called the court case a "witch hunt and said it was intended to stop him competing in the next presidential race.
