Iranian President Hassan Rouhani’s brother was sentenced to an unspecified term in prison for corruption, reported the semi-official ISNA news agency on Saturday.
Hossein Fereidoun, a close confidante of the president, will be able to appeal the verdict.
The financial misconduct charges date back to 2016, and were brought by hardliners who dominate the country's judiciary.
Rouhani changed his surname decades ago.
Fereidoun's trial began in February, and he's been free on bail since spending a night in prison in 2017.
He had played a role as part of the team that negotiated Iran's 2015 nuclear agreement with world powers.
Iran has in the past jailed allies of former presidents for similar charges.
