Sudan's protest leaders have announced plans to unveil a civilian body to take over from the country's ruling military council as huge crowds of demonstrators continued their days-long sit-in outside the army headquarters in the country's capital, Khartoum.

Protesters braved scorching heat and fatigue for a 14th day on Friday, demanding the military council, which took power after overthrowing longtime leader Omar al-Bashir, quickly make way for a civilian administration.

The Sudanese Professionals Association (SPA), which has been spearheading the months-long protests, said in a statement on Thursday that civilian council members would be named at a news conference at 17:00 GMT on Sunday outside the army complex to which foreign diplomats are also invited.

"We are demanding that this civilian council, which will have representatives of the army, replace the military council," Ahmed al-Rabia, a leader of the umbrella group of unions for doctors, engineers and teachers, told the AFP news agency.

The SPA and other groups behind the protests said the new transitional government should be made up of a presidential council tasked with carrying out the functions of the state, a council of ministers and a transitional civil statutory council.

A blueprint for the transition, proposed by the protest organisers, envisage a presidential council made up of "revolutionary figures" and a defence minister, the only representative from the military. It also said women should make up 40 percent of the legislative council.

Ahmed Adam, a Sudanese lawyer and research associate at SOAS University of London, said the military council was "reluctant to hand over power" and appeared to "lack solid political will to respond to the demands of the protesters on the ground".

"The military are counting on the divisions among the people on the streets to stay in power," Adam told Al Jazeera, adding: "The political civilian forces are still discussing the way to respond to this complicated transitional process. The expectations of the people are very high."
