stackja1945 is the first reader/Blair refugee to rise to my challenge to post at the ShadowLands. Turns out stackja's interest is history, and has offered the following excerpts from DM Horner's "Inside the War Cabinet". Thanks stackja:
D. M. Horner, Inside the War Cabinet
In October and November 1944 evidence was starting to mount from Allied radio intercept organisations that information in the Australian Military Forces Weekly Intelligence Review which had a wide distribution, was reaching Tokyo.
So far Blamey had tried to obtain action merely by stating, without evidence, that it was a matter of grave national security. He had no wish to explain the source of his information, nor widen the circle of people who might be aware of the leakage. However, to gain the action he considered necessary, he decided to enlist the help of Sir Frederick Shedden, and on 2 January 1945 explained the problem to the influential Secretary of the War Cabinet. Shedden recommended that Blamey write a more detailed letter to the Acting Minister for the Army, 'in view of the fact that he is the Minister primarily concerned with action to correct the leakages, if they are occurring on a Ministerial level or in another Department'.10 [Shedden to Blamey] This was a key sentence, because it indicates that the problem was not just a matter of information being obtained by the Chinese liaison officer, but that it was from a more serious source. It also explains Blamey's strong reaction to the Postmaster-General's Department consulting with the Department of External Affairs.
Blamey's letter to Senator Fraser, of 6 January 1945, must be seen in the light of this preceding correspondence. It read as follows: 15 [Blamey letter 3DRL 6643, 2/59]
As you know, the Allied Intelligence Organisation is now world wide and operates through many various channels, some of which are so secret that as little as possible in regard to them is set out on paper. One of its functions is to counter, as far as possible, the collection of Intelligence by the enemy. In the course of this service it has been definitely proved that there are leakages of information from Australia which have their origin apparently in Canberra.
