Sweden's Court of Appeal has refused a bid by WikiLeaks founder Julian Assange to have his case "set aside", ruling that no new information has emerged.
The computer programmer and publisher has been seeking refuge in London's Ecuadoran embassy since August 2012, after a Swedish court ruled to extradite him on charges of sexual assault and rape.
Assange claims that the decision could lead to a politically motivated deportation to the United States, where he is wanted in connection with charges of espionage following WikiLeak's public dissemination of classified American military information.
The appeal court said that after reviewing material in the case it found that the Australian was still a suspect in a sex allegation, which he has always denied.
In May, a Stockholm district court upheld an arrest warrant against Assange, who filed an appeal at Sweden's Court of Appeal, arguing that Sweden must comply with the UN group's findings that his deprivation of liberty was unlawful and that Sweden must release and compensate him for the harm caused.
WikiLeaks points out that the UK Government refuses to give any guarantees that Assange will not be extradited to the United States if he leaves the embassy.
The FBI and US Department of Justice informed a federal court in the United States that "prosecutive efforts" remain underway against WikiLeaks.
