I testified last week to the Chilcot inquiry. My experience demonstrates an emerging and dangerous problem with the process. This is not so much a problem with Sir John Chilcot and his panel, but rather with the government bureaucracy – Britain's own "deep state" – that is covering up its mistakes and denying access to critical documents.
There is only one solution to this problem, and it requires decisive action.
After I was invited to testify, I was contacted by the Foreign Office, from which I had resigned after giving testimony to the Butler inquiry in 2004, to offer its support for my appearance. I asked for access to all the documents I had worked on as Britain's Iraq "expert" at the UN Security Council, including intelligence assessments, records of discussions with the US, and the long paper trail on the WMD dossier.
