On the midnight of 7 and 8 October 1958, President Mirza ordered a mass mobilization of Pakistan Armed Forces and abrogated the Constitution after sending a letter to Prime Minister Feroz and the Constituent Assembly about the coup d'état. Most of the politicians became only aware of coup the next morning; only the U.S. Ambassador James Langley was kept aware of the political development in the country. President Mirza appointed General Ayub as its chief martial law administrator (CMLA) to enforce the martial law in both exclave–West and East Pakistan. However, President Mirza soon realized his mistake by making Ayub as the CMLA and repented his actions in news media about the delicate position he had gotten himself into. He regretted his decision and said: "I did not mean to do it," while offering assurances that the martial law would be for the shortest possible duration. In an attempt to consolidate the powers in his own control, Mirza unsuccessfully tried to appoint Ayub as Prime Minister the following and asked him to appoint the technocratic Cabinet. Such actions were not implemented due to Ayub Khan's protest against this attempt and briefly complained about Mirza's "high hand" methods. President Mirza made a bold move by undercutting Ayub's rival in the army, navy, marines, and air force by co-opting military officers in his favors. Informed of President Mirza's chicanery, Ayub dispatched the military unit to enter in presidential palace on the midnight of 26–27 October 1958 and placed him in a plane to exile in England. Subsequently, Admiral A. R. Khan and four persons: General Azam Khan, Nawab of Kalabagh Amir Khan, General Dr. Wajid Khan, and Air Marshal Asghar Khan were instrumental in Ayub Khan's rise to power.
