WikiLeaks founder Julian Assange is mounting an attempt to prevent his extradition from the UK to the US to face espionage charges.

The charges against the Australian citizen are in connection with the publication of hundreds of thousands of leaked documents about the Afghanistan and Iraq wars, as well as diplomatic cables, in 2010 and 2011.
