U.K. Home Secretary, Priti Patel, rubber stamped the transfer Friday after a court signed off on the decision. Assange has lost a series of legal battles to remain in the U.K. but WikiLeaks said that he plans to appeal the decision, meaning he’s unlikely to get on a plane any time soon.

Assange, has been in prison or in the Ecuadorian embassy in London for a decade, as he fought attempts to send him to face charges first in Sweden and then in the US. The government decision comes after a judge accepted US assurances over jail conditions. 

“The U.K. courts have not found that it would be oppressive, unjust or an abuse of process to extradite Mr. Assange,” a spokesperson for the Home Office said in a statement.

The Swedish case against him was dropped, but the US government in 2019 charged him under spying laws for his role in releasing hundreds of thousands of pages of classified documents via WikiLeaks, with the help of US Army intelligence analyst Chelsea Manning. 

Australian-born Assange is being held at high-security Belmarsh prison. 

Assange’s lawyers have previously indicated he has appeal options “including questions of free speech and on the political motivations of the US request.”

“It was in Priti Patel’s power to do the right thing,” WikiLeaks said in a statement. “Today is not the end of the fight. It is only the beginning of a new legal battle.” 

Supporters, that include several human rights and press freedom groups, have argued that the ruling leaves questions about the media’s ability to report from classified sources. WikiLeaks published diplomatic cables and emails including a video that showed a U.S. air strike that ended up killing a member of the Reuters news staff in Baghdad.
