At the end of 1930 Jamal had further meetings in London with British officials who liked his conciliatory approach. He agreed to proposals for a round table conference with members of the Jewish Agency. His one condition was that the Jewish delegates should come from Palestine and specifically that Weizmann should not be a member since this would be an act of recognition of validity of Zionist claims over Palestine. He returned to Palestine, in January 1931, feeling progress had been made. At this time he was also active as a journalist. In 1933 he published a series of anonymous articles in the Damascus newspaper "Alif Ba" in which he accused Awni Abd al-Hadi, leader of the new Independence Party, "Istiqlal", of selling 40,000 dunum of land in Wadi Hawarith to the Jewish Agency six years earlier. A 1937 Jewish Agency list has Jamal's name as having acted as an attorney in a similar land sale. It is an indication of how much information the Jewish Agency was collecting. Another example is a file which records discussions at an Executive Committee meeting, 12 April 1933, at which the imminent meeting, organised by Haim Arlosoroff, between Chaim Weizmann and leaders from Transjordan was discussed. The notes indicate that Jamal argued that the committee had no influence over tribal leaders east of the Jordan and that the meeting should be ignored.
