South Sudan’s parliament has named George Mabior Mayom as the acting chief whip of the Sudan People’s Liberation Movement-in-Opposition (SPLM-IO), replacing Farouk Gatkuoth Kam.

The announcement came Thursday during a parliamentary business committee meeting chaired by newly appointed First Deputy Speaker Ambrose Lomin Pitia. The committee convened to set the agenda for upcoming legislative discussions.

Mayom is part of the SPLM-IO faction led by Peacebuilding Minister Stephen Par Kuol, which has pledged cooperation with the government and the ruling Sudan People’s Liberation Movement (SPLM) to implement the 2018 peace agreement.

The SPLM-IO split in April after Par Kuol’s faction declared its own leadership and committed to working with the government to advance the peace deal.

Earlier this month, Speaker Jemma Nunu Kumba appointed Pitia as first deputy speaker, replacing Nathaniel Oyet Perino, who led the SPLM-IO faction loyal to suspended First Vice President Riek Machar.

Oyet was removed in August by presidential decree, which also revoked the appointments of Deng Deng Akon as speaker of the Council of States and Farouk Gatkuoth Kam as SPLM-IO chief whip. Oyet is currently in self-imposed exile but continues to lead Machar’s faction.

Machar was placed under house arrest in March and formally suspended last week by President Salva Kiir, who accused him of treason and crimes against humanity following a militia attack on a military base in Nasir County.

Several senior SPLM-IO officials, including Petroleum Minister Puot Kang Chuol and Army Deputy Chief of General Staff Gen. Gabriel Duop Lam, were arrested in connection with the incident.
