Floderus was arrested in Iran in 2022.
Iran said yesterday it had begun a trial of the Swedish national, having charged him with spying for Israel and “corruption on Earth”, a crime that carries the death penalty.
“He is entirely arbitrarily detained,” Kristersson told a press conference.
“We demand his immediate release.”
Relations between Sweden and Iran have been tense since 2019, when Sweden arrested a former Iranian official, Hamid Noury, on suspicion of torture and executions of political prisoners in Iran in the 1980s.
A Swedish district court in 2022 found Noury guilty of the charges.
Noury appealed the case, and an appeals court ruling is expected next week.
