Mr. Assange says the Geneva-based UN working group on arbitrary detention will publish its decision on his case on Friday. Jane Francis Kelly reports.

Julian Assange has not been charged with any offence, but he has been sought for questionning in Sweden in relation to sextual assault allegations made against him by two women. He has denied any wrongdoing, and has been living at the Ecuadorian embassy since June, 2012 after being granted asylum by its government. He claims the allegations are part of an attempt to have him extradicted to the US over the leaking on the Internet of sensitive diplomatic cables. He has said in a Twitt that if he loses the case against the UK and Sweden, he will leave the embassy at 12 noon on Friday, and hand himself over to the British police. Jane Francis Kelly.
