My circular D.66 8th November. 
Following for the Prime Minister:-
In view of the threatening situation on the German-Dutch frontier the question of His Majesty's  reply to the communication from the Queen of Holland and the King of the Belgians  is becoming matter of urgency. Draft reply is being considered by the War Cabinet this morning. Reply will of course indicate that it is sent on Ministerial advice and we naturally attach much importance to it being possibly stated that the Ministerial advice is that of His Majesty's Governments overseas as well as that of His Majesty's Government in the United Kingdom of Great Britain and Northern Ireland. In the hope that this course will be generally acceptable the draft reply will be framed so as to indicate this and we should be grateful if it were possible for you to telegraph at the earliest possible moment after receipt of the draft that you agree to the procedure proposed and that you are in agreement with the text of the draft reply.
It would facilitate consultation if you would repeat your reply to this telegram to the other three overseas Prime Ministers.
