WikiLeaks founder Julian Assange has lost his High Court bid to block extradition to Sweden, where he faces allegations of rape and sexual assault.
Two judges rejected claims that extraditing the 40-year-old Australian would be "unfair and unlawful".
Swedish authorities want him to answer accusations of raping one woman and sexually molesting and coercing another in Stockholm last year.
Assange, whose WikiLeaks website published a mass of leaked diplomatic cables that embarrassed several governments and international businesses, denies the allegations and says they are politically motivated.
On Wednesday the High Court upheld a ruling by District Judge Howard Riddle at Belmarsh Magistrates' Court, that the computer expert should be extradited to face investigation.
Assange was mobbed by his supporters as he approached the court building.
Fixed to the iron railings of the court were banners reading "Free Assange! Free Manning! End the wars".
