Former Brazilian President Jair Bolsonaro helped draft a plan to "redo the election" he narrowly lost in 2022, a co-accused testified on Monday in the former's trial over an alleged coup attempt.

Prosecutors accuse the 70-year-old far-right leader, who governed Brazil from 2019 to 2022, of having led a "criminal organization" plotting to wrest power from leftist election victor Luiz Inacio Lula da Silva.

The plot failed, the charge sheet says, for a lack of military backing.
