HL Deb 25 January 2001 vol 621 c22WA
Lord Hill-Norton

asked Her Majesty's Government:

What is the highest classification that has been applied to any Ministry of Defence document concerning Unidentified Flying Objects. [HL304]

Baroness Symons of Vernham Dean

A limited search through available files has identified a number of documents graded Secret. The overall classification of the documents was not dictated by details of specific sightings of "UFOs".
