Mohammed Omar's death was announced in July 2015 (he had died in 2013) and Akhtar Mansour was appointed his replacement as supreme leader of the Taliban. Hasan was one of several senior Taliban leaders who opposed Mansour's appointment and did not pledge allegiance to him.[1] Hasan wanted Omar's son Mohammad Yaqoob to be the leader,[7] and objected to the process and speed in which Mansour was appointed. It was rumoured that Hasan was expelled from the shura, but this was denied by Taliban spokesman Zabiullah Mujahid.
