WikiLeaks founder Julian Assange has filed an appeal today to take his case to the Supreme Court in a bid to block his extradition to Sweden on possible charges of sexual assault and rape.

The High Court will decide whether Assange is allowed to appeal to the Supreme Court at a hearing on 4 December. The court may though delay handing down its decision.

Assange could take his case directly to the Supreme Court if the High Court refuses his appeal, but there is no guarantee his case would be heard.

The latest appeals filing comes after Assange lost a second appeal in the High Court on 2 November. The two judge panel found that the European Arrest Warrant issued for Assange was proportionate and valid, and the offences alleged against him are criminal in both the UK and Sweden.

In his first extradition hearing in February, Assange's legal team connected Sweden's extradition attempt to WikiLeaks' continuing release of some 250,000 secret US diplomatic cables.

After losing the second appeal Assange said that the European Arrest Warrant structure is so strict that it prevents courts from considering the facts of a case. He emphasised he hadn't been charged with a crime.
