According to reported, a division bench comprising Judge Lord Justice Thomas and Mr Justice Ouseley gave their verdict in his appeal against a European arrest warrant issued by Swedish prosecutors after rape and sexual assault accusations made by two Swedish women following his visit to Stockholm in August 2010.
Theguardian said that Assange could be handed over to Sweden within 10 days.
According to the newspaper, Assange has 14 days to seek leave to appeal to the supreme court if he believes there is a wider issue of “public importance” at stake in the decision.
It wrote that If he was successful in persuading the high court of that, he was likely to remain on conditional bail until a hearing, which was unlikely to take place until next year.
If he is denied the right to appeal then British law enforcement officers will be responsible for arranging his removal to Sweden within 10 days, the theguardian reported
