A convention of Muslim League held in Karachi in September 1962 which was presided by Nawab Muhammad Amin, who was supporter of the 1962 constitution.

[3] The Convention Muslim League was formed on the basis of support for politician and military general Muhammad Ayub Khan in 1962.

His Industrialist, Western style policy made him Liberal and Secularist in the eyes of many 'Pakistan' Muslim League leaders, therefore he was deeply unpopular and the party splintered, some who favored Ayub Khan and some who did not.

[4] Ayub Khan used the Convention Muslim League as his ruling party to gain legitimacy in order to seem as a follower of the democratic process during his martial law.

[5] Ayub Khan was generally considered by many Islamists on the Far-right as a Liberal, due to his Western attire and somewhat Secular policies.
