Furious Richard Ratcliffe slammed Mr Johnson’s attempts to set his wife free and dubbed the battle to get her released a “test of endurance”.
As the second anniversary of her shocking detention looms, Mr Ratcliffe raged: “We didn’t expect to be needing to mark this anniversary – not after the hopes of Christmas and the Foreign Secretary’s word.
“But it remains a cold late Spring. Nazanin was told that if she wasn’t home by Christmas, at least it should be done by Nowruz, and we should worry if we go past March 2018, with the storms that might lie ahead. And now we have.”
He added: “Our story has become a test of endurance, and there is a need to recharge spirits – particularly after the disappointment of the Foreign Secretary’s mission failing to deliver, and Nazanin becoming caught up in this government stand off – so we wanted the anniversary to be an occasion where we drew positive energy.
“That is what the outside can do, and we are grateful for people’s care.”
Tulip Siddiq, Ms Zaghari-Ratcliffe’s MP, also criticised Mr Johnson.
She said: “In November the Foreign Secretary promised to ‘leave no stone unturned’. But since his trip to Tehran, he has been missing in action.
“Nazanin does not have the luxury of time, and Boris Johnson must act before her situation gets worse.
She added: ”If he can’t deliver on this, then it is time that the Prime Minister stepped in.”
The Free Nazanin campaign also jumped in and questioned whether Mr Johnson has “given up on his promise to bring home Nazanin soon”.
The campaign has also told the Foreign Secretary’s office that it is a contortion to claim that her case is just a normal consular case.
Supporters said: “Given that Nazanin is held for something the government has not done, not because of something she has, the claim she is just another consular case belittles the government’s obligations.”
Ms Zaghari-Ratcliffe is serving a gruelling five-year jail term after being convicted of spying charges.
She was arrested on April 3, 2016 and hauled in front of a judge.
She vehemently denied the charges and to this day maintains she was in Iran to introduce her young daughter Gabriella to her parents.
Mr Ratcliffe said his wife has suffered panic attacks in her sleep.
A Foreign Office spokeswoman said: “On the second anniversary of Nazanin’s arrest we continue to approach her case, and all of our British-Iranian consular cases, in a way that we judge is most likely to secure the outcome we all want.
“Therefore we will not be providing a running commentary on every twist and turn.”
