Background on Conviction
He was determined responsible of orchestrating a conspiracy aimed at retaining his authority after he failed to win the national vote to his left-wing rival, Lula.
Supreme Court justices said that he was aware of a plan which encompassed plans to murder Lula and his vice-presidential running mate, Alckmin, and to imprison and murder Alexandre de Moraes - the Supreme Court justice who has been overseeing his judicial proceedings.
The plot was stopped because it couldn't obtain the support of the army and air force commanders. The current president was took office without problem on the first day of 2023.
But a week later, on 8 January, many Bolsonaro supporters stormed and vandalised official structures in the capital, the capital city.
