The ruling party, SPLM, has dissolved its entire leadership structure with exception of the office of President Salva Kiir, the party chairman.
This came in an extra-ordinary meeting of the National Liberation Council chaired by President Kiir on Friday.
Officials say the move means the SPLM in Opposition leader, Riek Machar, and incumbent vice president, James Wani Igga, are no longer the deputies to Kiir.
Pagan Amum, who was also recently reinstated to the position of secretary general, has lost the post, again.
The former Secretary for Popular Syndicated Mobilization, Martin Majut, told the media that the President is expected to appoint the new leadership body within a month.
“The chairman is empowered to appoint new secretaries in the national secretariat as soon as possible,” Mr Majut said.
Meanwhile, analysts believe that the dissolution will have impact on the inter-SPLM party dialogue which sought to maintain the leadership prior to December 2013 crisis in the young country.
