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 in order 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.
