Katharine Gun writes: Following the damning Chilcot report, much will be said about the decision to go to war in Iraq. But one thing will be missing: the information I leaked in the runup to the war. It won’t get an airing because I was never questioned or asked to participate in the Chilcot inquiry.

Back in early 2003, Tony Blair was keen to secure UN backing for a resolution that would authorise the use of force against Iraq. I was a linguist and analyst at GCHQ when, on 31 Jan 2003, I, along with dozens of others in GCHQ, received an email from a senior official at the National Security Agency. It said the agency was “mounting a surge particularly directed at the UN security council (UNSC) members”, and that it wanted “the whole gamut of information that could give US policymakers an edge in obtaining results favourable to US goals or to head off surprises”.

In other words, the US planned to use intercepted communications of the security council delegates. The focus of the “surge” was principally directed at the six swing nations then on the UNSC: Angola, Cameroon, Chile, Bulgaria, Guinea and Pakistan. The Chilcot report has eliminated any doubt that the goal of the war was regime change by military means. But that is what many people already suspected in 2003.

I was furious when I read that email and leaked it. Soon afterwards, when the Observer ran a front-page story: “US dirty tricks to win vote on Iraq war”, I confessed to the leak and was arrested on suspicion of the breach of section 1 of the Official Secrets Act. I pleaded not guilty and, assisted by Liberty and Ben Emmerson QC, offered a defence of necessity – in other words, a breach of the law in order to prevent imminent loss of human life. This defence had not and, to my knowledge, has still not, been tested in a court of law.

I believed that on receiving the email, UK parliamentary members might question the urgency and motives of the war hawks, and demand further deliberations and scrutiny. I thought it might delay or perhaps even halt the march towards a war that would devastate Iraqi lives and infrastructure already crushed by a decade of unrelenting sanctions. A war that would send UK and US service men and women into harm’s way, leaving hundreds of them dead, disfigured and traumatised. Unfortunately, that did not happen. It couldn’t, for now we know via Chilcot that Blair promised George W Bush he would be “with him, whatever”. [Continue reading…]
