British businessman Christopher Tappin has pleaded guilty to selling surface-to-air missile parts to Iran, at a court hearing in El Paso, Texas.
Christopher Tappin, 66, of Orpington, Kent, had pleaded not guilty but changed his plea at a hearing in El Paso, Texas, after an agreement with US prosecutors.
His guilty plea, to one count of the indictment, calls for a 33-month sentence which prosecutors have said they will not oppose him serving back in the UK.
Christopher Tappin will be sentenced on 9th of January. In addition to the prison term of 33 months Tappin's plea deal includes a fine of $11,357.14 - the projected profit he stood to gain if his illegal activity had been brought to fruition.
He was originally thought to have faced up to 35 years in jail if found guilty.
His wife Elaine, 62, said ahead of today's hearing that "however upsetting" a plea deal was, it marked the beginning of his "swift and safe return" to the UK.
The case followed an investigation which started in 2005 when US agents asked technology providers about buyers who might have raised red flags.
Those customers were then approached by undercover companies set up by government agencies.
Tappin has admitted that between December 2005 and January 2007 he knowingly aided and abetted others in an illegal attempt to export zinc/silver oxide reserve batteries, a special component of the Hawk Air Defence Missile, to Iran.

But the Prime Minister adds: "Of course, balancing these arrangements is absolutely vital but I think it is important that at the same time we remember why we enter into these extradition treaties, which is to show respect to each other's judicial processes and make sure that people who are accused of crimes are tried for those crimes. Britain can benefit from that as well."
