Katharine Gun
Explore the story of Katharine Gun (born 1974), the British linguist and whistleblower who leaked a secret memo in 2003 exposing U.S.–U.K. efforts to spy on UN diplomats ahead of the Iraq war. Learn about her background, the leak, her trial, her legacy, and her voice.
Introduction
Katharine Teresa Gun (née Harwood; born 1974) is a British linguist, translator, and whistleblower. She gained public prominence in 2003 after leaking a top secret memo that revealed how the United States, with British cooperation, was seeking intelligence on diplomats from countries on the U.N. Security Council. Her decision to expose this “dirty tricks” plan placed her in conflict with the British government under the Official Secrets Act, and raised fundamental questions about war ethics, secrecy, and dissent. Her story later became the subject of the film Official Secrets.
Gun’s act was not just a moment of personal courage; it also resonated as a symbol of moral responsibility in the face of governmental secrecy and war. Her example continues to inspire debates about whistleblowing, democratic accountability, and the limits of state power.
Early Life & Education
Katharine Teresa Harwood was born in 1974.
While in Taiwan, Gun attended Morrison Academy until around age 16. Moira House School, a girls’ boarding school in Eastbourne.
Later, in 1993, she entered Durham University, studying Japanese and Chinese (Mandarin). She graduated with an upper second-class degree.
Her path to intelligence work came later. After returning to the UK and trying various jobs, in 2001 she applied for a linguist role at GCHQ (Government Communications Headquarters), the UK’s signal intelligence agency. She later said she had little idea at the time what exactly the organisation did.
The Leak: Exposing the Memo
Discovery of the Memo
While working at GCHQ as a translator (especially translating Mandarin Chinese into English), Gun encountered a sensitive email on 31 January 2003 from an NSA staffer named Frank Koza. The memo requested GCHQ’s help in surveilling UN diplomats from certain non-permanent Security Council member states (e.g. Angola, Cameroon, Chile, Pakistan, Guinea) to uncover compromising information. The intent was to influence their vote in favor of a U.N. resolution backing the invasion of Iraq.
Gun believed this request was unethical and possibly illegal. Over a weekend, after contemplation, she printed a copy of the memo and passed it to a friend, who in turn passed it to journalists at The Observer.
The Observer published the story in March 2003 under the headline “US dirty tricks to win vote on Iraq war”.
Confession and Arrest
After the publication, Gun confessed to her line manager at GCHQ that she had leaked the memo and was arrested shortly afterward.
In November 2003, she was formally charged under section 1 of the Official Secrets Act 1989. Her case became widely publicized and drew international attention.
Trial & Outcome
Gun’s trial was scheduled for 25 February 2004. However, in a highly unusual turn, the prosecution dropped the case before presenting evidence.
Why did the case collapse? The timing raised significant speculation: the defense had requested disclosure of legal advice given to the UK government—particularly whether British legal advisers believed the Iraq war might be unlawful. A full trial might have exposed that material. Some observers argue that the government dropped the prosecution to prevent those documents from becoming public.
On the day, Gun said:
“I’m just baffled in the 21st century [that] we as human beings are still dropping bombs on each other as a means to resolve issues.”
During the proceedings, many civil rights groups and public figures rallied to her support. The drop of the case meant she walked free.
Later Life & Legacy
After Effects
After the trial, Katharine Gun faced challenges in reentering secure work, as her case made it difficult for employers to trust her with classified roles. Turkey with her husband Yaşar Gün, a Turkish Kurd, and their daughter.
In January 2020, she gave an opening speech at a workshop on retaliation organized by scholars concerned with whistleblowing and ethics.
Public & Cultural Impact
Gun received the Sam Adams Award in 2003 in recognition of her courage. Her case became emblematic for whistleblower advocates in the UK and beyond.
Her story was dramatized in the 2019 film Official Secrets, starring Keira Knightley as Gun. The film brought renewed awareness to the leak and the moral dilemmas she faced.
Daniel Ellsberg, famed for leaking the Pentagon Papers, praised her act as “in some ways more significant” than his own.
Her decision to act has become a case study in ethics, law, journalism, and international relations—particularly questions of when breaking secrecy is justified by higher moral duty.
Personality, Motivation & Values
Katharine Gun often says she never intended to become a whistleblower; but when confronted with an email she found unethical and dangerous, she felt she had no choice.
Her convictions seem rooted in belief in accountability, transparency, and the idea that citizens should not be misled into war. The leak was motivated less by personal ambition and more by a sense of duty to truth.
In interviews, she has admitted the emotional, legal, and financial strain her decision caused her life and family. Her courage lies in choosing risk for principle, not comfort or fame.
