After a years-long legal saga, Wikileaks says that founder Julian Assange has left the UK after reaching a deal with US authorities that will see him plead guilty to criminal charges and go free.
Mr Assange, 52, was charged with conspiracy to obtain and disclose national defence information.
For years, the US has argued that the Wikileaks files – which disclosed information about the Iraq and Afghanistan wars – endangered lives.
For the last five years, he has fought extradition to the US from a British prison.
Mr Assange also faced separate charges of rape and sexual assault in Sweden, which he denied.
He spent seven years hiding in Ecuador’s London embassy, claiming the Swedish case would lead him to be sent to the US.
Swedish authorities dropped the case in 2019 and said that too much time had passed since the original complaint, but UK authorities later took him into custody.
He was tried for not surrendering to the courts to be extradited to Sweden.
Assange will return to Australia, according to a letter from the justice department.
On X, the platform formerly known as Twitter, Wikileaks said that Mr Assange left Belmarsh prison on Monday after 1,901 days in a small cell.
He was then “released at Stansted airport during the afternoon, where he boarded a plane and departed the UK” to return to Australia, the statement added.
Video shared online by Wikileaks appear to show Mr Assange, dressed in jeans and a blue shirt, being driven to Stansted before boarding an aircraft.
His wife, Stella Assange, posted on X thanking his supporters “who have all mobilised for years and years to make this come true”.
The deal – which will see him plead guilty to one charge of the Espionage Act – is expected to be finalised in a court in the Northern Mariana Islands on Wednesday, 26 June.
The remote Pacific islands, a US commonwealth, are much closer to Australia than US federal courts in Hawaii or the continental US.
She said the priority for her husband is to “get healthy again”, be in touch with nature, and for the family to have “time and privacy”.
Stella also confirmed that the couple’s two children are in Australia with her, but she has not yet told them that he is to be freed, only that they were going to visit family and that there was “a big surprise” waiting for them.

Agence France Press quoted a spokesperson for Australia’s government as saying that the case had “dragged on for too long”.
Mr Assange and his lawyers had long claimed that the case against him was politically motivated.
In April, US President Joe Biden said that he was considering a request from Australia to drop the prosecution against Assange.
In a victory the following month, the UK High Court ruled that Mr Assange could bring a new appeal against extradition to the US, allowing him to challenge US assurances over how his prospective trial would be conducted and whether his right to free speech would be infringed.
After the ruling, Stella told reporters and supporters that the Biden administration “should distance itself from this shameful prosecution”.
