Julian Assange to appeal to UK Supreme Court against extradition to US

London: WikiLeaks founder Julian Assange is appealing the British government’s decision to order his extradition to the US.

The appeal was filed in the Supreme Court on Friday (London time), the latest twist in a decade-long legal saga sparked by the publication of classified US documents on its website. Further details about the profession were not readily available.

Assange’s supporters staged protests this weekend ahead of his 51st birthday, with his wife Stella Assange among people gathered outside the UK’s Home Office to demand his release from prison.

The Australian has been fighting in British courts for years to avoid being sent to the US, where he faces 17 charges of espionage and one of computer abuse charges.

US prosecutors say he helped US military intelligence analyst Chelsea Manning steal secret diplomatic cables and military files that WikiLeaks later published, putting lives at risk. Manning was pardoned by President Barack Obama.

To his supporters, Assange is a secret-breaking journalist who exposed US military misconduct in Iraq and Afghanistan.

A British court ruled in April that he could be sent to trial in the US and sent the case to the British government for a decision. Interior Secretary Priti Patel signed an order on June 17 authorizing the extradition of Assange.

The Australian government is under mounting pressure to intervene, but last month Prime Minister Anthony Albanian rejected calls for him to publicly demand that Washington stop the prosecution of Assange.
