A French academic charged with spying in Iran after last year's disputed election will be allowed to leave the country on Sunday, says her lawyer, BBC reported.
Clotilde Reiss, who has been staying at the French embassy in Tehran on bail, has had the main charge against her dropped, according to her lawyer.
The 25-year-old was accused of taking part in protests that erupted after last June's presidential election.
She has been ordered to pay a fine of $300,000 (£200,000) for lesser charges.
Her lawyer, Mohammad Ali Mahdavi, said on Saturday he had paid the sum on her behalf, although he did not specify the reduced charges.
A spokesman for the French foreign ministry, Bernard Valero, told news agency AP that France was "awaiting her return without delay".
Ms Reiss, a university lecturer, was arrested last July and bailed a month later.
She had been on a six-month teaching and research assignment in the central city of Isfahan.
The development comes a week France freed an Iranian engineer whom it detained for allegedly exporting electronic parts illegally to sell to Iran's military.
The US had wanted to extradite Majid Kakavand, but a French court rejected the request last week and he was allowed return home.
