(b) That the Head of the Army Section and the Head of the Air Section of the Mission should be of General Officer or equivalent rank. (c) If and when a new Head of the Mission is appointed he should be provided with a letter of introduction from the Prime Minister to Premier Stalin. (d) An agreed charter should be drawn up, as a result of discussions on a high level, in which should be laid dawn the particular items of information to be exchanged between the Russians and ourselves. Once such a charter had been drawn up, we should insist that the Mission had direct and easy access to all the items contained therein.
