Mr Tappin was handcuffed and put on a flight to El Paso, Texas, where he was expected to land at 4pm local time. The retired businessman described his treatment as a "disgrace" as he arrived at Heathrow police station to be taken to America to face arms dealing charges. Mr Tappin, who fought a two-year battle against extradition, faces up to 35 years in jail if convicted of conspiring to sell components for Iranian missiles. His lawyer Karen Todner said: "Mr Tappin has been taken now by British extradition officers to the aeroplane, where he is going to be handed over to US marshals. "He will be arriving in El Paso this afternoon. He will be appearing in court on Monday morning, so he will be in custody over the weekend."
