Flávio Bolsonaro, Brazil’s leading rightwing presidential hopeful, has been caught on tape asking a banker accused of corruption for $26.8m (£20m) to fund a film about his father, the former president Jair Bolsonaro . The leaked voice memos and text messages were published on Wednesday by the Intercept Brasil, and later acknowledged by Flávio Bolsonaro, a far-right senator who is tied in polls with President Luiz Inácio Lula da Silva ahead of October’s election. The incident was already being seen as the most serious blow since the senator announced his candidacy as his father’s representative, since the former president is under house arrest after being convicted over an attempted coup. In the recordings, Flávio Bolsonaro can be heard asking for R$134m ($26.8m) towards a “heroic” biopic in which Jair Bolsonaro is played by Jim Caviezel, who portrayed Jesus in Mel Gibson’s 2004 Passion of the Christ.…
