British-Iranian dual national Alireza Akbari, who was sentenced to death in Iran, has been executed.
Mr Akbari’s family had been asked to go to his prison for a “final visit” on Wednesday and his wife said he had been moved to solitary confinement.
The ex-deputy Iranian defence minister was arrested in 2019 and convicted of spying for the UK, which he denied.
UK Prime Minister Rishi Sunak said the execution was a “callous and cowardly act, carried out by a barbaric regime”.
Iran’s rulers had “no respect for the human rights of their own people” Mr Sunak said, adding that his thoughts were “with Alireza’s friends and family”.
