WikiLeaks founder Julian Assange's fight to avoid facing spying charges in the United States may be nearing an end following a protracted legal saga in the U.K. that included seven years of self-exile inside a foreign embassy and five years in prison. Assange faces what could be his final court hearing in London starting Tuesday as he tries to stop his extradition to the U.S. The High Court has scheduled two days of arguments over whether Assange can ask an appeals court to block his transfer. “His life is at risk every single day he stays in prison,” Stella Assange said Thursday.
