This Saturday is 1,900 days since his arrest - he has not seen his family for over five years. The Foreign Office told me that during the nuclear negotiations, they did not once bring up my dad's detention with Iran. I think that was a missed opportunity... We must not rest until my dad is back home with his wife, daughter, son and two granddaughters. We have all suffered for too long. Theresa May, please do everything you can to help free Grandpa Kamal before it is too late.
