Next Monday, London will begin hearings to decide whether Australian Julian Assange should be extradited to the United States.
The decision will come almost a decade after WikiLeaks angered Washington by publishing classified documents in the U.S.
Assange spent seven years hiding in the Ecuadorian embassy in London before being arrested last April. He is wanted by the US on 18 criminal charges of conspiracy to hack into government computers and violate an espionage law. If convicted, the WikiLeaks founder could spend decades in prison.
Protesters in London marched on Saturday from Australia House to Parliament Square. The protest featured banners declaring "freedom of the press" and "Journalism is not a crime.".
The demonstration was supported by Roger Waters , formerly of Pink Floyd , British fashion designer Vivienne Westwood , and singer-songwriter Chrissie Hynde Pretenders , who gave a short performance for the demonstrators who participated in the march.
