Input: Question: How old was President Ayub Khan when he founded the first Parkistan Muslim League? Passage:The Pakistan Muslim League (; known as PML), is the name of several different Pakistani political parties that have dominated the Right-wing platform since the 1960s. The first "Pakistan" Muslim League was founded by President Ayub Khan in 1962 as a successor to the original Muslim League. Just a short period after its foundation, the party broke into two factions: Convention Muslim League that supported the President and the new Constitution, and the Council Muslim League, that opposed the new Constitution, denouncing it as undemocratic that made the Presidency an autocratic position. Following President Ayub's resignation, Nurul Amin, a right-wing political veteran, attempted to reunite the factions of Pakistan Muslim League. His efforts were supported by some, while opposed by others. Before the 1970 Elections, a senior leader of Council Muslim League, Abdul Qayyum Khan formed his own variant of the Muslim League that opposed cooperation with a party that once supported a Dictator. In 1973, Amin's efforts succeeded and the Functional Muslim League (PML-F) was founded.
