Following from Prime Minister for Prime Minister-
We have been considering further the system of collaboration
between the Governments of the British Commonwealth with the
object of examining whether any suggestion could be put forward
for securing the closest possible contact and co-operation.

2. We have been much impressed by the value of the meetings with
Dominion Ministers in London last Autumn which took place
following upon the suggestion conveyed in Circular D.19 of 21st
September. [1]

3. The problems confronting us are of such importance and the need
for our being completely satisfied that we fully understand and
can meet each other with any point of view is so important that I
feel that the time has now come when the best course is to arrange
for a meeting of Prime Ministers. In the present circumstances,
such a conference, to obtain the greatest advantages, should be
near the seat of war, and I would therefore suggest that it be
held in London. I appreciate the difficulties which the Dominions
Prime Ministers might well feel in leaving their own countries in
the present circumstances, but, notwithstanding these
difficulties, the advantages of such a meeting are so great that I
trust that you will find it practicable to arrange to attend. I
should be glad to arrange a time most convenient to you and the
other Prime Ministers; subject to your views, I should be inclined
to suggest that July or early August of this year might be most
suitable.

4. I should be glad to learn from you at your early convenience
whether you agree in general with the proposal for the holding of
such a conference, and, if so, whether you would be able to come
to London at the time suggested. I should not contemplate that
anything in the nature of a detailed agenda need be prepared. The
subjects for discussion would clearly be the joint war effort in
all its aspects and an opportunity might be afforded for, at any
rate, preliminary consideration of the problems of post war
reconstruction. But if there are any particular problems which you
would wish to see raised, you would no doubt let me know.

5. If it is decided to hold such a conference, it would, I think,
be desirable that every precaution should be taken on security
grounds to keep the intention secret as long as possible.
