Under the leadership of Sir Sikandar Hayat Khan, the party won the general elections of 1936 and formed a coalition government along with the Indian National Congress and Sikh Akali Dal from 1937 onwards. However, in October 1937, the Muslim members in the party were also allowed to merge with the All India Muslim League by an agreement reached between Sir Sikandar and Mr Muhammad Ali Jinnah at Lucknow. This famous agreement was called the Jinnah-Sikandar Pact.
