The 52-year-old Assange is wanted in the US for espionage, and faces 18 charges related to the publication of a range of highly classified information relating to the US-led wars in Afghanistan and Iraq.

Next week, the High Court of Justice in the UK will hold its hearing into whether Mr Assange can appeal his extradition to the US.

Mr Assange has been held in London’s high-security Belmarsh prison since 2019 and potentially faces up to 175 years in prison.
