Despite President Mugabe's calls for unity, observers described the rivalry between supporters of Mnangagwa and Mujuru as the most serious division within ZANU–PF in 30 years. Mujuru garnered a large amount of support in ZANU–PF's politburo, central committee, presidium, and among the provincial party chairs. Mnangagwa's support came from the senior ranks of the security establishment, as well as parts of ZANU–PF's parliamentary caucus and younger party members. The rivalry was ethnic as well as political: Mnangagwa drew his support from members of his ethnic group, the Karanga, while Mujuru's supporters were largely Zezuru.
