Public reporting in March and April 2026 points to Mojtaba Khamenei exercising power mostly through directives, written messages, and intermediaries, not through public negotiations. Reports describe him as Iran’s new supreme leader after the death of his father, Ayatollah Ali Khamenei [16][

Those accounts described his first foreign-policy line as hard and retaliatory, though one report noted it was not clear whether he attended the relevant session in person or remotely .
