Sudan's Rapid Support Forces will sign a charter with allied political and armed groups on Saturday evening to establish a "government of peace and unity" in territories it controls, signatories al-Hadi Idris and Ibrahim Mirghani told Reuters.
The RSF has seized most of the western Darfur region and swathes of the Kordofan region in an almost-two-year war, but is being pushed back from central Sudan by the Sudanese army, which has condemned the formation of a parallel government.
Such a government, which has already drawn an expression of concern from the United Nations, is not expected to receive widespread recognition. Those affiliated with the government say its formation will be announced from inside the country.
General Mohamed Hamdan Dagalo, head of the paramilitary that has been accused of widespread abuses including genocide, was hit with sanctions by the United States earlier this year.
The war, which erupted after disagreements between the RSF and the army over their integration during a transition towards democracy, has devastated the country, driving half the population into hunger.
According to Idris, among the signatories to the charter and foundational constitution is powerful rebel leader Abdelaziz al-Hilu who controls vast swathes of territory and troops in South Kordofan state, and who has long demanded that Sudan embrace secularism.
Talks that began earlier this week were hosted in Kenya, drawing condemnation from Sudan and domestic criticism of President William Ruto for plunging the country into a diplomatic melee.
