A British couple detained in Iran have lost their appeal against lengthy prison sentences on espionage charges, their family confirmed on Wednesday. The development comes as the Foreign Office intensifies diplomatic efforts to secure their release.
The couple, who have not been named due to legal restrictions, were arrested in early 2023 while travelling in the country. They were convicted in a closed trial in Tehran and sentenced to 10 years each for allegedly spying for British intelligence. The family’s statement described the appeal ruling as a “devastating blow” and called on the UK government to do more.
The Foreign Office said it was “urgently” raising the case with Iranian authorities. A spokesperson described the sentences as “wholly unjust” and reiterated calls for consular access, which has been repeatedly denied. The UK has designated Iran as a state of concern for arbitrary detentions, citing similar cases in recent years.
Analysts note that the appeal’s rejection aligns with a pattern of judicial intransigence in Tehran, where espionage cases often serve as leverage in wider geopolitical negotiations. The UK’s soft power options remain limited, given the absence of a functioning bilateral dialogue. Pressure now focuses on multilateral forums, including the UN Human Rights Council.
The couple’s health is reported to be deteriorating, according to family sources. A Foreign Office minister described the situation as “extremely grave” in a private briefing to MPs. The UK has previously secured the release of dual nationals through quiet diplomacy, but the current administration faces criticism for a perceived lack of urgency.
International human rights groups have condemned the trial as lacking due process. The case underscores the risks faced by foreign nationals in Iran, where anti-Western sentiment has been stoked by state media. The couple’s fate now hinges on whether the Foreign Office can leverage economic or diplomatic incentives to secure a pardon or release.
