I thank my hon. Friend for his comments and supportive statements over the weekend. I share his deep concerns about this unacceptable leak for exactly the reasons that he has clearly set out, and I reassure him that it is being treated with the full seriousness that it deserves. There will be a cross-Government investigation, led by the Cabinet Office. Obviously it is not for me to prejudge the inquiry, but I can assure him, and the House, that it will be comprehensive and that, as with all leak inquiries, it will endeavour to report its findings clearly—and if evidence of criminality is found, then yes, the police could be involved. The most important focus is to establish who is responsible for this despicable leak.
Again, I am grateful that my hon. Friend’s experience in the Army and in international affairs has been able to lend a voice of authority to the condemnation that we should all wish to express.
