A 15-member transitional military council was named, chaired by Gen. Suwar ad-Dahhab, in 1985. In consultation with an informal conference of political parties, unions, and professional organizations—known as the "Gathering"—the military council appointed an interim civilian cabinet, headed by Prime Minister Dr. Al-Jazuli Daf'allah. Elections were held in April 1986, and a transitional military council turned over power to a civilian government as promised. The government was headed by Prime Minister Sadiq al-Mahdi of the Umma Party. It consisted of a coalition of the Umma Party, the Democratic Unionist Party (DUP) (formerly the NUP-National Unionist Party), the National Islamic Front (NIF) of Hassan al-Turabi, and several southern region parties. This coalition dissolved and reformed several times over the next few years, with Prime Minister Sadiq al-Mahdi and his Umma Party always in a central role.
