What the ruling orders

Hours after the result of the Brazil election put Lula back in the presidential seat, supreme court justice Alexandre de Moraes – who also oversaw the coup trial of the senator's father Jair Bolsonaro – imposed the travel ban as part of a criminal case in which the federal police are investigating Flávio Bolsonaro over possible involvement in a money-laundering scheme.

The ruling sets out several measures:

• All of his passports are cancelled, including the diplomatic one he holds as a congressman.
• He must hand them over within 24 hours.
• He may not leave Brazil while the investigation continues.
• He is barred from any contact with Willer Tomaz, a lawyer linked to betting companies suspected of being used to launder about £680m.

Bolsonaro announced it himself

The senator was the first to speak publicly about the order, appearing in a video before Brazilian media even knew of the judge's decision. He said he had just visited his father, who is under house arrest in Brasília, when officers arrived to serve the document.

The brother's interview and the family's response

According to the senator, the decision stemmed from an interview his brother Eduardo Bolsonaro gave last Friday urging him to leave Brazil. Eduardo, who lives in self-imposed exile in the US, told a US podcast that day that he favoured his brother departing if he lost the election.

Legal troubles pile up

The Flávio Bolsonaro passports order adds to a growing list of problems for the senator. Like his father four years earlier, he has not conceded defeat to Lula, and his party issued a statement on Monday night acknowledging the result while saying the questions raised should be clarified through democratic debate.

• When his Senate term ends early next year, he will be out of public office for the first time in 24 years, and therefore without the special jurisdiction afforded to officeholders.
• He faces a separate criminal investigation over the £20m he was captured on tape asking a disgraced banker accused of corruption to provide for a biopic about his father.

According to the newspaper Folha de S.Paulo, he had been persuaded to drop his plan to seek annulment of the election, which he had announced after the result was declared on Sunday night. He had argued the two-hour extension of voting – intended to let voters reach polling stations via the mandatory free public transport – had harmed the election. His own campaign, however, had also argued for the extension, and allies and lawyers told him the argument was legally weak.

Instead, he said in the video that he would file another case seeking the disqualification of Lula's ticket over alleged abuse of economic power.
