A federal judge sentenced a British businessman to nearly three years in prison Wednesday for trying to buy surface-to-air missile parts from undercover U.S. agents to resell to Iran.

Christopher Tappin, 66, pleaded guilty in November to aiding and abetting to export defense materials in a deal that opened the door for him to serve part of his sentence in Britain near his ailing wife. U.S. District Judge David Briones in El Paso, Texas, said Wednesday that he would recommend that the U.S. Department of Justice approve any request by Tappin to be transferred to the United Kingdom.
