A retired British businessman is being extradited to the U.S. for allegedly selling batteries for Iranian missiles, The Guardian reports. Christopher Tappin, 65, handed himself into authorities at Heathrow airport after a two-year legal battle. A former president of the Kent Golf Union, Tappin could face up to 35 years in prison if convicted in an American court, though he maintains he’s innocent and is the victim of entrapment. His high-profile case has drawn criticism of the U.K.’s extradition arrangements with both the U.S. and Europe. “I look to [David] Cameron to look after my rights, and he has failed to do so,” Tappin told The Guardian.
