In May, Clayton Balfour stated that in response to the indication that the agreement had been shaken, «It allowed for a significant revision to be necessary in light of the changes that have taken place in the situation since the development of the agreement,» but that he nevertheless felt that «the agreement applies anyway.» The following eleven points included the formal agreements between Great Britain, France and Russia. In the Constantinople Agreement of 18 March 1915, after naval operations began in the run-up to the Gallipoli campaign, Russian Foreign Minister Sergei Sazonov wrote to the French and British ambassadors to claim Constantinople and the Dardanelles. During a five-week series of diplomatic talks, the United Kingdom and France, although they made their own claims, agreed on greater influence in Iran in the case of the United Kingdom and on the annexation of Syria (including Palestine) and Cilicia for France. The demands of the United Kingdom and France were unanimous and all parties agreed to leave the exact management of the holy sites to a subsequent settlement.  Without the Russian revolutions of 1917, Constantinople and the Strait could have been given after the Allied victory over Russia. This agreement and the Sykes-Picot agreement were complementary, because France and Great Britain had to satisfy Russia first to conclude the partition of the Middle East.  The Anglo-French statement was read in samonic, and Pichon commented that it showed the selfless position of the two governments towards the Arabs and Lloyd George that it was «more important than all the old agreements».  Pichon mentioned an agreement proposed on 15 February on the basis of the private agreement between Clemenceau and Lloyd George last December.  (According to Lieshout, Clemenceau presented Lloyd George, just before Faisal met at the conference of 6, a proposal that seems to cover the same subject; Lieshout, which issued on British materials related to the 6, while the date is not specified in the minutes.  At a meeting in a railway car in Saint-Jean-de-Maurienne, On 19 April 1917, an interim agreement was reached between british and French Prime Ministers David Lloyd George and Alexandre Ribot, the Italian Prime Minister and Foreign Ministers Paolo Boselli and Sidney Sonnino, in order to respond to Italian interest in the Ottoman Empire, in particular Article 9 of the Treaty of London.  The agreement was necessary by the Allies to secure the position of the Italian armed forces in the Middle East.
