The SPA, which spearheaded months of protests that led to the ouster of former President Omar al-Bashir on April 11, is part of an opposition coalition that has held three meetings since Saturday with the Transitional Military Council (TMC).
Sudanese protest leaders on Sunday vowed to escalate demonstrations to confront the country’s military rulers.
The Sudanese Professionals Association, which was at the forefront of the protest campaign that toppled longtime president Omar al-Bashir this month, said it would announce the civilian council at 1700 GMT.
The deposed Sudanese president Omar al-Bashir was moved from his residence to Kobar prison in the capital Khartoum, two family sources said on Wednesday, and a prison source said he was being held under tight security in solitary confinement.
The organisation that spearheaded the protests against Bashir, the Sudanese Professionals Association, called on the council “to immediately transfer power to a civilian government”.
