Last weekend saw the two sides sign a deal paving the way for civilian rule
Sudan's military leaders and opposition alliance have formed a sovereign council to lead the country during its three-year transition to civilian rule.
Made up of six civilians and five military officers, it will initially be led by Lt-Gen Abdel Fattah Abdelrahman Burhan.
He took over as Sudanese leader following the overthrow of President Omar al-Bashir.
The council will be sworn in on Wednesday morning.
A prime minister is expected to be sworn in later that day.
The latest moves were announced by a spokesman for the ruling Transitional Military Council (TMC).
