Wikileaks founder Julian Assange has failed in his appeal against extradition from the UK to Sweden over allegations of rape and sexual assault. Two judges at the High Court in London decided that a previous ruling in favour of extradition must be upheld. Swedish authorities want him to answer accusations of raping one woman and sexually molesting and coercing another in Stockholm last year. Mr Assange's lawyers say they will appeal at the Supreme Court. They now have 14 days to take the case to the highest court in the land, on the grounds that it raises issues of general public importance. 'Accurate description' In February, District Judge Howard Riddle ruled that Mr Assange should be extradited to face investigation following a hearing at City of Westminster Magistrates' Court. The 40-year-old Australian denies the allegations and says they are politically motivated. However, in their ruling the judges, the President of the Queen's Bench Division Sir John Thomas, sitting with Mr Justice Ouseley, said that the issuing of the European arrest warrant (EAW) that led to Mr Assange's arrest and all subsequent proceedings to achieve extradition was "lawful" and "proportionate". They dismissed Mr Assange's argument that the warrant was invalid because it had been issued by a prosecutor, and not a "judicial authority". They also said the action of the prosecutor was subject to the independent scrutiny of Swedish judges, "which, as judges of another (EU) member state, we must respect". The court also rejected Assange's assertion that the descriptions of the offences were not a fair and accurate description of the conduct alleged against him. 'Level playing field' Wikileaks has published a mass of leaked diplomatic cables which have embarrassed several governments and international businesses. American soldier Bradley Manning is being held in US custody for allegedly leaking information to the website. Dressed in a navy blue suit and wearing a Remembrance Day poppy, Mr Assange was mobbed as he approached the court building. Police redirected him away from the crowd who had fixed to the iron railings of the court banners reading "Free Assange! Free Manning! End the wars". Speaking after the appeal hearing, his supporters outside the court said they were "outraged" by the judges' decision. Ciaron O'Reilly, 51, said: "Assange is probably the most amazing person in recent history who's upset so many powerful people in such a short space of time so it's obviously not a level playing field."
