Julian Assange, the founder of WikiLeaks, has reached a plea deal with the US Justice Department, allowing him to plead guilty to a conspiracy charge and potentially freeing him after five years in a British prison. The deal relates to the publication of classified documents, including tens of thousands of activity reports about the wars in Afghanistan and Iraq. Assange will appear in court in the Northern Mariana Islands to plead guilty and is expected to be sentenced to 62 months, with credit for time served. He is likely to return to Australia after the proceedings.
