On 16 July 1937, in connection with the intensified efforts made in London by the Polish government intent on securing the inclusion of Poland into international negotiations pertaining to the Western Pact, the Polish Ministry of Foreign Affairs received from the Foreign Office the text of an appendix to a successive British memorandum containing the principles on which the future pact should be based. In response, on 27 August 1937 the Polish government presented to the British cabinet a memorandum which officially formulated a stand proposed to the British upon many previous occasions, namely, that the Pact should not omit the question of Polish security. The suggestion also contained a motion about supplementing the negotiated two-partite Pact by means of a third, French-German-Polish component. Emphasis was placed on the fact that a pact referring to Polish interests, but negotiated without the participation of Poland, could not be accepted by the latter. The Foreign Office, however, decided that if the Polish government wanted to obtain a guarantee that the German eastern frontier would be taken into account in the same fashion as the Polish western frontier, then His Majesty's government would not participate in any sort of a pact concerning Eastern Europe. At the same time, the British expressed the conviction that the Polish government would regard a Polish-French treaty as a sufficient guarantee, and entirely omitted the Polish-German context. The hopes which the Polish side linked with the appendix proved to be unfounded..
