The first Vice-President of South Sudan, Riek Machar, has been accused of “leadership failure” by a top official of his Sudan People’s Liberation Movement in Opposition (SPLM-IO) party.
The official, secretary-general Tingo Peter, tendered his resignation on Tuesday after serving in the role for four years.
He accused Mr Machar of failing to “display good leadership” and running the party without consultations.
Mr Machar’s office has not responded to the accusations.
“You have run the movement without transparency, especially when it comes to decision making process. You don’t respect the institution’s structures established by the movement’s constitution,” Mr Peter wrote in his resignation letter.
He said his resignation will not affect the implementation of a peace agreement signed by Mr Machar and his political rival President Salva Kiir in 2018 after years of conflict.
