British interior minister Priti Patel has approved the extradition of WikiLeaks' founder Julian Assange to the United States to face criminal charges, bringing his long-running legal saga closer to a conclusion.
Assange is wanted by US authorities on 18 counts, including a spying charge, relating to WikiLeaks' release of vast troves of confidential US military records and diplomatic cables which they said had put lives in danger.
Wikileaks said Assange would appeal his extradition.
"Today is not the end of the fight. It is only the beginning of a new legal battle. We will appeal through the legal system," a statement posted on the Wikileaks Twitter accounts said.
His supporters say he is an anti-establishment hero who has been victimised because he exposed US wrongdoing in conflicts in Afghanistan and Iraq, and that his prosecution is a politically-motivated assault on journalism and free speech.
"On 17 June, following consideration by both the Magistrates Court and High Court, the extradition of Mr Julian Assange to the US was ordered. Mr Assange retains the normal 14-day right to appeal," the Home Office said in a statement.
"In this case, the UK courts have not found that it would be oppressive, unjust or an abuse of process to extradite Mr Assange," the Home Office said in a statement.
"Nor have they found that extradition would be incompatible with his human rights, including his right to a fair trial and to freedom of expression, and that whilst in the US he will be treated appropriately, including in relation to his health."
Originally, a British judge ruled that Assange should not be deported, saying his mental health problems meant he would be at risk of suicide if convicted and held in a maximum security prison.
But this was overturned on an appeal after the United States gave a package of assurances, including a pledge he could be transferred to Australia to serve any sentence.
Patel's decision does not mean the end of Australian-born Assange's legal battle which has been going on for more than a decade.
He can launch an appeal at London's High Court which must give its approval for a challenge to proceed. He can ultimately seek to take his case to the United Kingdom Supreme Court.
But if an appeal is refused, Assange must be extradited within 28 days.
"This is a dark day for press freedom and for British democracy," Assange's wife Stella said. "Today is not the end of the fight. It is only the beginning of a new legal battle."
