United Democratic Salvation Front or UDSF Western Bahr El Ghazal Youth League released a press statement condemning former secretary general for acting unilaterally against the party constitution.
Youth Chairman Abdalla Ziada Taban told Voice of Hope that the former national secretary-general David Biil was ousted out through the 2012 national convention that was held in Juba.
He complained that Mr Biil was still acting as party secretary-general despite his removal from the position.
Mr Ziada said he was still nominating candidates for political positions in the government.
He added that such acts were undermining the mandate and powers of the current UDSF executive office.
Mr Ziada called for the immediate dismissal of Mr Biil from the party.
Voice of Hope could not reach the former UDSF national secretary-general for comment.
