I have had a rigorous check made on your communication that correspondence between you and me had been divulged, through the fault of the Soviet Embassy in London, in particular Ambassador F. T. Gusev. The verification showed that neither the Embassy as such nor F. T. Gusev personally is to, blame in the least and, in fact, does not even have some of the documents the contents of which were divulged by British newspapers. In other words, the leak came from the British, not the Soviet side. Gusev is willing for any investigation to prove that neither he nor any member of his staff has had anything to do with divulging the contents of our correspondence. It appears that you have been misled as to Gusev and the Soviet Embassy.
