After invoking their authority to “sack” Negeri Sembilan ruler Tuanku Muhriz Tuanku Munawir, the state's territorial chieftains are now going after Menteri Besar Aminuddin Harun.

In a letter yesterday, the Undang Yang Empat - together with another state chieftain, the Tunku Besar Tampin - called for the members of the Negeri Sembilan state assembly to remove Aminuddin from office.
