Richard Ratcliffe has issued an urgent plea to Boris Johnson to help free his wife, Nazanin Zaghari-Ratcliffe, who has been detained in Iran for over five years.
Speaking to Yahoo News UK from outside the Foreign Office, where he is on the 18th day of a hunger strike, Ratcliffe called on the prime minister to honour a promise he says he made to pay off a £400m debt to the Iranians that could expedite the release of his wife.
Zaghari-Ratcliffe, a British-Iranian dual national, was captured by the Iranian authorities during a family visit with her daughter in 2016 on charges of plotting to overthrow its government. The family have consistently denied the claims against her.
