Bolsonaro's defiance on fleeing to Florida signalled continued upheaval for Brazil, where leftist President Luiz Inacio Lula da Silva won a dramatic runoff election Sunday.

"I am the elected president, and the criminals who stole Brazil's election are part of a criminal organisation that has established a tyranny," Bolsonaro said in the statement published on his X account, slamming "electoral fraud".
