Live Updates: Assange's Father and Legal Team Talk to Press Ahead of Extradition Hearing - Video

"Of course, we are working on the possibility to ask the French authorities to provide political asylum [to Assange]. Our constitution allows this", Dupond-Moretti said at a press conference.

John Rees of the Stop the War Coalition assessed the visit by Shadow Chancellor John McDonnell saying that the MP was both personally glad to see him and took it as a sign that support is broadening for the campaign to prevent Assange from being extradited.

"I think anybody who has been in Belmarsh prison for the length of time he has been there would be finding life tough and undoubtedly he is. But he is a very focused, very strong individual. And we had a very informative and wide-ranging discussion with him", Rees said.

Rees also addressed the upcoming demonstration rally this Saturday, saying there is a great deal of international support for the demonstration on Monday.

"I think there is international, global interest in this case – I think it is a global cause. On Monday, there will be a demonstration here at Belmarsh but there are also going to be demonstrations in cities across the world from Australia to the West Coast of America. So I think you can see from that this is a dynamic, determined movement which has seen that there is a gross injustice being perpetrated and they are determined to put an end to it", he concluded.
