LSIB/411/53. 

9th December, 1953. 

United States Communications Intelligence Board. 

In paragraph 3 of the covering memorandum to the 

Report on the U.K.-U.S. Conference on the Communications 

Security of N.A.T.O. Countries held at Washington in June 1953, 

it was recommended that a copy of the Report itself should be 

forwarded, with certain cormnents, to the appropriate Canadian 

authorities. · 

2. No action has hitherto been proposed by the U.K. 

to implement this recommendation, since it was thought that 

the best time to approach the Canadians would be when the 

U.S. and the U.K. had reached full agreement on the action 

to be ta.ken on the Conference proposals. Since it is understood that the U.S. has not yet passed the Report to the 

Canadians, it is assumed that U.S. implementation of the 

recommendation has been delayed for similar reasons. 

3. As action on the Conference proposals now appears 

inuninent L.S.I.B. considers that the approach to the Canadians 

should be made forthwith. May I suggest that the U.S., as the 

host nation of the Conference, should send a copy of the Report 

to the Communications Research Cormnittee in Ottawa on behalf 

of both U.S.C.I.B. and L.S.I.B.? If you agree to this procedure 

I should be grateful if you would make it clear to the Canadians 

that it was adopted at the suggestion of the U.K.
