Following the merger, Al-Haidari became a politburo member of the Communist Party.[3] Al-Haidari became a close associate of the new general secretary Salam Adil, and together Adil and al-Haidari constituted one of the two politburo fractions (the other, nicknamed the 'Clique of Foor' was led by Baha ud-Din Nuri). Towards the late 1950s, the situation in the politburo deteriorated. The 'Clique of Foor' accused Adil and al-Haidari of spoiling the relations with Abd al-Karim Qasim.[4]
