"We have been told by the Foreign Office they are working on it, but it is more complicated because the Iranians chose to see him as an American... we are now trying to shed light and ask questions because he should never have been left behind as a British citizen," Roxanne added.

Former UK Foreign Secretary Jeremy Hunt believes Tahbaz's US citizenship is being used by IranÌý.

"The Iranians want something from the Americans before they're prepared to release him," Hunt said.Ìý

US State department Spokesman Ned Price has also questioned Iran's motives, while insisting thatÌýsecuringÌýTahbaz's release isÌý"an utmost priority".

"Simply put, Iran is unjustly detaining innocent Americans and others and should release them immediately," Price told reporters.

After his 2018 arrest, Tahbaz was sentenced to 10 years in prison for "assembly and collusion against Iran's national security" and working for the United States as a spy. Tahbaz and human rights groups have strongly denied the charges.
