Julian Assange, the elusive founder of WikiLeaks, is expected to appear in a UK court tomorrow, The Guardian reports. The news comes after his lawyers announced he would meet police to discuss an extradition warrant from Sweden that relates to alleged sexual assaults. U.S. attorney general Eric Holder has said he’s authorized “a number of things to be done” to combat WikiLeaks, which has been publishing sensitive documents. Meanwhile, Assange will likely face a long court battle to avoid extradition. The precise time of his interview with police isn’t known, but he’s expected to have to post bail of up to £200,000 and would require up to six people offering surety. Once he turns himself over to police, he’ll have to appear before a magistrates court within 24 hours to seek release on bail. A full hearing of the extradition case would have to be heard within 28 days.
