Official Secrets is a 2019 British drama film directed by Gavin Hood, based on the case of whistleblower Katharine Gun who exposed an illegal spying operation by American and British intelligence services to gauge sentiment of and potentially blackmail United Nations diplomats tasked to vote on a resolution regarding the 2003 invasion of Iraq. Keira Knightley stars as Gun, alongside Matt Smith, Matthew Goode, Adam Bakri, Indira Varma and Ralph Fiennes.
The film had its world premiere at the Sundance Film Festival on 28 January 2019 and was released in the United States on 30 August 2019, by IFC Films, and in the United Kingdom on 18 October 2019, by Entertainment One.
Plot
In early 2003, GCHQ analyst Katharine Gun obtains a memo detailing a joint United States and British operation to spy on diplomats from several non–permanent United Nations Security Council member states Cameroon, Chile, Bulgaria and Guinea to "dig dirt" on them and influence the Security Council into passing a resolution supporting an invasion of Iraq. Angered that the United Kingdom is being led into a war on false pretences, Katharine leaks the memo to a friend involved in the anti-war movement, who passes it to anti-war activist Yvonne Ridley, who in turn passes it to The Observer journalist Martin Bright.
The Observer foreign editor Peter Beaumont allows Martin to investigate the story in the interests of journalism. To verify the authenticity of the leaked memo, Martin enlists the help of the Observer's Washington, DC correspondent Ed Vulliamy in contacting the memo's author Frank Koza, the Chief of Staff at the "regional targets" section of the National Security Agency. Despite the Observer pro-war stance, Peter convinces the newspaper’s editor Roger Alton that the leaked memo is worth publishing.
The publication of the leaked memo in March 2003 generates considerable public and media interest. The Drudge Report attempts to discredit the document as a fake after a young staffer named Nicole Mowbray inadvertently changed the text from American to British English using spell check. However, Martin is able to produce the original memo, confirming its authenticity. Katharine's actions prompt GCHQ to launch an internal investigation. Seeking to prevent an invasion of Iraq and to protect her fellow GCHQ colleagues from prolonged suspicion, Katharine confesses to leaking the memo. She is arrested and detained for a night before being released on remand.
Following the outbreak of the Iraq War, Katharine seeks the services of the Liberty lawyers Ben Emmerson and Shami Chakrabarti. The British Government decides to charge her with violating the Official Secrets Act, tasking Director of Public Prosecutions Ken Macdonald with leading the prosecution. To exert pressure, the British authorities attempt to deport her husband Yasar Gun, a Turkish Kurd. However, Katharine is able to halt the deportation by presenting a marriage certificate proving the authenticity of her relationship.
Ben comes up with the defence strategy that Katharine was acting out of loyalty to her country by seeking to prevent the UK from being led into an unlawful war in Iraq. With the help of Martin, Ed, and former Foreign Office deputy legal adviser Elizabeth Wilmshurst, Ben discovers that the Attorney General Peter Goldsmith changed his position on the legality of the Iraq War after meeting with several lawyers from the Bush Administration. Despite the odds stacked against them, Katharine refuses to plead guilty in exchange for a reduced charge.
On the day of the trial, the Crown prosecutor drops all charges against Katharine. Ben suggests to the court that this is because prosecuting her would have shown that the Blair government led the UK into war on false pretences. The film then mentions the human toll of the Iraq War and that Lord Goldsmith's advice on the illegality of the Iraq War was made public in 2010. The film ends with footage of Katharine addressing the media following the dismissal of her case and Ben shunning Ken for putting Katharine through the ordeal "to make an example of her".
