WikiLeaks founder Julian Assange has lost his appeal in a British court against extradition to Sweden, where he faces rape accusations. Lord Justice Thomas and Justice Ouseley on Wednesday said the 40-year-old Australian should face Swedish prosecutors about the alleged rape of one woman and sexual assault of another following his visit to Stockholm in August 2010. Assange insists the case is politically motivated. Should he successfully bring forward another appeal, he will be heard in front of the British supreme court. If he is denied the appeal, he will have to leave for Sweden within 10 days.
