Background: Julian Paul Assange (; ne Hawkins; born 3 July 1971) is an Australian computer programmer and the editor of WikiLeaks. Assange founded WikiLeaks in 2006, but came to international attention in 2010, when WikiLeaks published a series of leaks provided by Chelsea Manning. These leaks included the Collateral Murder video (April 2010), the Afghanistan war logs (July 2010), the Iraq war logs (October 2010), and CableGate (November 2010). Following the 2010 leaks, the federal government of the United States launched a criminal investigation into WikiLeaks and asked allied nations for assistance.
Context: Assange visited Sweden in August 2010. During his visit, he became the subject of sexual assault allegations from two women with whom he had sex. He was questioned, the case was initially closed, and he was told he could leave the country. In November 2010, however, the case was re-opened by a special prosecutor who said that she wanted to question Assange over two counts of sexual molestation, one count of unlawful coercion and one count of "lesser-degree rape" (mindre grov valdtakt). Assange denied the allegations and said he was happy to face questions in Britain.  In 2010, the prosecutor said Swedish law prevented her from questioning anyone by video link or in the London embassy. In March 2015, after public criticism from other Swedish law practitioners, she changed her mind and agreed to interrogate Assange in the Ecuadorian embassy in London, with interviews finally beginning on 14 November 2016. These interviews involved police, Swedish prosecutors and Ecuadorian officials and were eventually published online. By this time, the statute of limitations had expired on all three of the less serious allegations. Since the Swedish prosecutor had not interviewed Assange by 18 August 2015, the questioning pertained only to the open investigation of "lesser degree rape", whose statute of limitations is due to expire in 2020.  On 19 May 2017, the Swedish authorities dropped their investigation against Assange, claiming they could not expect the Ecuadorian Embassy to communicate reliably with Assange with respect to the case. Chief prosecutor Marianne Ny officially revoked his arrest warrant, but said the investigation could still be resumed if Assange visited Sweden before August 2020. "We are not making any pronouncement about guilt", she said.
