On 7 July, Cabinet Secretary, you told me in a written reply that you did not expect that civil servants were involved in the leaking of this information, and I believe that has now been confirmed by the Permanent Secretary. On 14 August, you told me that you were satisfied that special advisers were not responsible for the leaking of this information. That doesn’t leave many people left in the frame, Cabinet Secretary, so can I ask you simply this: do you know who leaked the information?
