An academic from Exeter who was jailed for spying in the United Arab Emirates is filing a formal complaint against the British government over the way it handled his case.
Durham University PhD student Matthew Hedges was sentenced to life imprisonment by the Gulf state last year after being accused of working for MI6.
He was pardoned in November, although officials continued to call him a spy, which he denies.
He said the Foreign Office did not take "effective and timely" action to secure his release.
His wife, Daniela Tejada, explained to BBC Devon why they felt they needed to make the formal complaint.
Foreign Secretary Jeremy Hunt says the government has taken the situation seriously and has been "very effective".
