TOP SECRET ANNEX INTELLIGENCE ORGANISATION FOR A SUPREME HEADQUARTERS The Working Party agreed that in order to produce a chart, certain assumptions must be made from the information available. These assumptions are:(a) that in a future war, a Supreme Commander, when appointed, will be concerned with highlevel policy, major strategy, political implications, economic problems and the co-ordination of the three services: (b) that in view of these responsibilities of a Supreme Commander, his appointment will be kept distinct from that of any of the three Service Commanders-in-Chief, in that he will not be required to carry out the functions of a Supreme Commander as well as those of Commander-in-Chief of one of the Services.
