This vilayet extended southwards to the Gulf of Aqaba but excluded most of Palestine. While some British governments occasionally stated that the intent of the McMahon Correspondence was not to promise Palestine to Hussein, they have occasionally acknowledged the flaws in the legal terminology of the McMahon–Hussein Correspondence that make this position problematic. The weak points of the government's interpretation were acknowledged in a detailed memorandum by the Secretary of State for Foreign Affairs in 1939. A committee established by the British in 1939 to clarify the arguments said many commitments had been made during and after the war and that all of them would have to be studied together. The Arab representatives submitted a statement from Sir Michael McDonnell to the committee that said whatever meaning McMahon had intended was of no legal consequence because it was his actual statements that constituted the pledge from His Majesty's Government. The Arab representatives also said McMahon had been acting as an intermediary for the Secretary of State for Foreign Affairs, Lord Grey. Speaking in the House of Lords on 27 March 1923, Lord Grey said he had serious doubts about the validity of the Churchill White Paper's interpretation of the pledges he, as Foreign Secretary, had caused to be given to the Sharif Hussein in 1915. The Arab representatives suggested a search for evidence in the files of the Foreign Office might clarify the Secretary of State's intentions.
