A file of correspondence, meeting minutes and memoranda concerning secret service responsibilities in Greece, Egypt and the Middle East, recording a debate between the Security Service (MI5) and the Secret Intelligence Service (MI6) over which organisation had responsibility for the covert acquisition of intelligence in the region. The documents include memoranda and letters from both services setting forth their cases, letters between officials discussing the dispute, and minutes of the meetings in which the dispute was resolved (in favour of MI6). Amongst the topics of discussion are the differing roles of the services; the distinction between covert and overt intelligence gathering; the problems caused by competing intelligence agencies; the legacy of ad hoc wartime intelligence organisation; and the necessity of having separate organisations.
