The former Labour leader joined dozens of protesters ahead of Mr Assange's court appearance today.
Westminster Magistrates’ Court is formally expected to issue an order to extradite the WikiLeaks founder after years of legal toing and froing.
It will then be down to Home Secretary Priti Patel to approve, although defence lawyers may yet appeal to the High Court.
The administrative hearing is expected to be brief, and Mr Assange may not attend in person.
Mr Assange is wanted in the US over an alleged conspiracy to obtain and disclose national defence information following WikiLeaks’ publication of hundreds of thousands of leaked documents relating to the Afghanistan and Iraq wars.
He has always denied wrongdoing.
Mr Assange, who married his fiancee Stella last month, has been held in Belmarsh prison for three years since being dragged out of the Ecuadorian embassy in London.
