Hassan al-Turabi
In 1977, a National Reconciliation took place between Sadiq al Mahdi, the leader of the opposition who was based abroad, and Nimeiry. A limited measure of pluralism was allowed and Sadiq al Mahdi and members of the Democratic Unionist Party (Sudan) joined the legislature under the umbrella of the Sudan Socialist Union. Hassan al-Turabi, an Islamist leader who had been imprisoned and then exiled after the May Revolution, was invited back and became Justice Minister and Attorney General in 1979. Relations between Khartoum and the South Sudan leadership worsened after the National Reconciliation and the National Reconciliation itself came to a premature end in light of disagreements between the opposition and Nimeiry.
