Facing allegations of sexual assault in Sweden, Julian Assange (pictured), the founder of WikiLeaks, requested asylum at the Ecuadorian embassy in London.

Assange v Swedish Prosecution Authority were the set of legal proceedings in the United Kingdom concerning the requested extradition of Julian Assange to Sweden for a "preliminary investigation" into accusations of sexual offences allegedly made in August 2010. Assange left Sweden for the UK in 27 September 2010 and a warrant for his arrest was issued in his absence the same day. He was suspected of rape of a lesser degree, unlawful coercion and multiple cases of sexual molestation. In June 2012, Assange breached bail and sought refuge at Ecuador's Embassy in London and was granted asylum.

Julian Paul Assange is an Australian editor, publisher, and activist who founded WikiLeaks in 2006. He came to international attention in 2010 after WikiLeaks published a series of leaks from Chelsea Manning, a United States Army intelligence analyst: footage of a U.S. airstrike in Baghdad, U.S. military logs from the Afghanistan and Iraq wars, and U.S. diplomatic cables. Assange has won over two dozen awards for publishing and human rights activism.

WikiLeaks is a non-profit media organisation and publisher of leaked documents. It is funded by donations and media partnerships. It has published classified documents and other media provided by anonymous sources. It was founded in 2006 by Julian Assange. Kristinn Hrafnsson is its editor-in-chief. Its website states that it has released more than ten million documents and associated analyses. WikiLeaks' most recent publication of original documents was in 2019 and its most recent publication was in 2021. From November 2022, numerous documents on the organisation's website became inaccessible. In 2023, Assange said that WikiLeaks is no longer able to publish due to his imprisonment and the effect that US government surveillance and WikiLeaks' funding restrictions were having on potential whistleblowers.
