2. MARKING OF BRITISH CLASSIFIED DOCUMENTS SECRET THE COMMITTEE considered a minute+ by the Secretary covering a minute by M.I.6, stating that they had found that, owing to the peculiarities of their work, their internal system of handling papers (all of which were treated in the same way as Top Secret papers were treated in other Departments) and the large volume of reports and documents passed to Ministries, etc., with whose varied practices they complied in each case, the detailed application to their Department of the system of marking British classified documents contained in the instruction approved* by the Joint Intelligence Committee was not practicable, and they therefore asked to be released from that obligation except in the case of documents which were being sent to the Americans.
