Reference Bruce's telegram S.57 repeated to Washington. 
I think Bruce's contact with the Polish Ambassador quite unnecessary. Bruce was informed by me of the matter and the procedure to be adopted; namely a clear indication that no action was necessary in London.  He knew that the Prime Minister has authorized me to deal with Churchill.  The United Kingdom was acting for the Commonwealth in duly obtaining the Polish Government's consent. There the matter ended in London. Bruce's intervention increases the risk of premature disclosure and consequent embarrassment. Bruce is not our Minister to the Polish Government. For instance, it would be inappropriate for formal letter referred to in S.99 to go through Bruce when United Kingdom acting for us.
You will agree to this point of view. Please watch Bruce's cables closely in order to keep me informed of any others of similar nature. This, coming on top of his asking for Officer be appointed Minister , confirms the suspicion that the two have been in communication on the matter without reference to you or me. Having reference to the previous conduct of Officer , wish you to be on your guard throughout all these negotiations.
