The former political detainees, who also describe themselves as SPLM leaders’ group, said they want a new leadership to emerge during revitalization of the 2015 peace accord.

SPLM-FDs is a faction made up of senior ruling party officials who were detained when the conflict began in December 2013.

The former detainees group’s spokesman Kosti Manibe Ngai confirmed to Radio Tamazuj on Friday that they had unveiled a road map for President Kiir and former vice president turned rebel leader Riek Machar to exit power and allow the formation of a new government.

“It is actually a document and it is our proposal for public debate. We hope that when the High Level Revitalization meeting is held, those would be some of the proposals to be discussed,” said Kosti.

“Leadership should emerge from the debate and I think before you talk about individuals, you first need to be clear in terms of the problem that we are facing and the solution that we agree on,” he added.

When asked whether foreign minister Deng Alor and transport minister John Luk who are still serving in the unity government in Juba were part of the document, Kosti said: “This is a document of the SPLM-FDs and they are part of SPLM-DFs.”

On Friday, Kiir’s administration reacted angrily after the former political detainees unveiled a proposal advocating for departure of President Kiir and his archrival Riek Machar.

 “They are part of the government, so if they have decided to rebel, they are free to rebel,” Michael Makuei Lueth, Information Minister said.

“When the council of ministers of IGAD came, the SPLM-FDs declined to attend the meeting as part of the TGoNU, so if they are not part of TGoNU they are free to say whatever they want to say, but that’s not the position of the government,” he added.

In June, the leaders of the Intergovernmental Authority on Development (IGAD), the regional bloc comprising Djibouti, Ethiopia, Kenya, Somalia, South Sudan, Sudan, and Uganda endorsed the creation of a High Level Revitalization Forum (HLRF) to bolster the essentially defunct 2015 peace agreement.
