Citation: Memorandum from R.G. Robertson to Mr. Carter (2 April 1975).
See the attached copy of a memorandum I have prepared for the Prime Minister to pull together a number of the things that he will want to have in mind before speaking to the Premiers as he plans to do – probably at the time of his dinner on April 9th.
You will recall that the other day I asked you to give some thought to the question the Prime Minister had raised with me as to whether there should be reference, either at the outset or early in discussions, about the “fall back” position. I gave the matter some thought over the weekend and you will see, beginning on page 5, a suggestion that I have made to the Prime Minister. There will be ample time to discuss this further and if you have any different view please let me know.
