Damian Green arrest; why did they lie?

On 8th October 2008 Chris Wright, Director of Security and Intelligence at the Cabinet Office, wrote to Bob Quick in the following terms:

A number of recent leak investigations, including some conducted by your officers, have raised questions about the security of sensitive information in the Home Office. Whilst not all the leaks that concern us merit, taken individually, investigation by the police, we are concerned that there is an individual or individuals in the Home Office with access to sensitive material who is (are) prepared to leak that information. We are in no doubt that there has been considerable damage to national security already as a result of some of these leaks

On 16th April the Director of Public Prosecutions, Kier Starmer, published his report into the CPS examination of the case and said:

The information contained in the documents was not secret information or information affecting national security: it did not relate to military, policing or intelligence matters. It did not expose anyone to a risk of injury or death. Nor, in many respects, was it highly confidential. Much of it was known to others outside the civil service, for example, in the security industry or the Labour Party or Parliament.

Now no one would suggest that the Director of Security and Intelligence is unable to tell the difference between a State secret and a bit of political intelligence embarrassing to a government Minister.

So where, Mr Wright, is your evidence of 'considerable damage to national security'?

Or did you just make it all up?
