According to Melvyn Leffler, Churchill sought to “abolish” the percentage agreement after the end of the world war and the image of Greece.  This was particularly the case, with Churchill and Roosevelt keeping such discretion over the agreement that their successors in power did not know it. Meanwhile, Stalin initially believed that the secret agreement was more important than Yalta`s public agreement, which led to his perception of betrayal and the growing urgency to secure friendly governments on the ussr`s border.  Winston Churchill proposed the agreement under which the United Kingdom and the USSR agreed to divide Europe into spheres of influence, one country being “predominant” in one area and the other “predominant” in another.  Churchill harboured at least part of the substance of the agreement the hope that the British could land in Yugoslavia and cross the Ljubljana breach, which would require cooperation with the Red Army, which had already entered Yugoslavia.  Moreover, Churchill`s interest in removing EAM from power interested him in persuading Stalin, whose support for the EAM was so far largely rhetorical, to abandon EAM, because he did not want the disagreements over Greece to be the occasion for an Anglo-Soviet struggle in the Balkans.  In the British transcript of the conversations, Churchill`s main concern was that the imminent prospect of civil war in Greece could be at the root of an Anglo-Soviet war in which the Soviets supported the EAM and the British.  After the discussion on Poland, Churchill stated that Romania was “a Russian affair” and that the ceasefire between the Soviet Republic and Romania was “reasonable and showed a great deal of state art in the interest of general peace in the future”.  Churchill went on to say that “Britain must be the first Mediterranean power,” which requires having Greece in the British sphere of influence.  Stalin expressed some sympathy for the British who, for much of world War II, were unable to use the Mediterranean because of the risk of maritime and air strikes by Axis powers stationed in Italy, forcing the British to supply their troops to Egypt on the long way around the Cape of Good Hope.  An agreement was quickly reached with Greece and Romania, but Bulgaria, Yugoslavia and Hungary became more difficult.
 In his famous biography of Churchill, Roy Jenkins writes that the agreement “proposed spheres of influence of real politics in the Balkans. The [Churchill] report reported that “The Americans would be shocked if they saw how crudely he had said it.”  Historian David Carlton notes in the same way that “[with the October Treaty], a clear, albeit informal, agreement had been reached on the most important point: he had Stalin`s agreement to treat Greece as he sees fit.”  Anthony Eden wrote that he and Churchill had discussed the subject months before the meeting and that “we felt entitled to ask for Soviet support for our policy towards Greece, in exchange for our support for Soviet policy towards Romania.” The British historian Richard Crampton described the agreement with Churchill and Stalin as “famous” in a “capitable” way that divided Eastern Europe into spheres of influence without consulting the peoples concerned.  The Percentages Agreement (also known as the “Naughty Document”) was an agreement between Soviet Prime Minister Joseph Stalin and British Prime Minister Winston Churchill on the division of different European countries into spheres of influence at the Fourth Moscow Conference in 1944.
