Zambia's President Levy Mwanawasa announced on Monday that he has sacked his vice president, Nevers Mumba, for insubordination. According to Mwanawasa, Mumba had breached an oath of allegiance when he failed to retract his recent allegations that the Democratic Republic of Congo (DRC) was harbouring individuals who were working against the Zambian government. Mumba will be replaced by Northern Province Minister Lupando Mwape.
