Mujib's senior cabinet minister Khondakar Mushtaq Ahmad formed a new government and immediately initiated a few critical changes in Mujib's policies and rules of business in government. However, within three months the first military coup took place in Bangladesh by senior members of the army, removing Mushtaq and replacing his administration. Armed forces personnel alongwith internal political and government forces fell into a chaotic dispute, resulting in a vacuum at the highest level of government.
