The Pakistani Republican Party was formed in October 1955, by a break away faction of the Muslim League and other politicians supporting the creation of the West Pakistan province, on the instigation of key leaders in the military and civil service. The President of the party was Dr Khan Sahib, Chief Minister of West Pakistan. The main instigator behind this development was Iskander Mirza, the then Governor General of Pakistan. He was the vice president of this party and later became the inaugural President of Pakistan in 1956. The Central Parliamentary Leader was Sir Feroz Khan Noon, Prime Minister of Pakistan (1957 - 1958).
