Mugabe died at a hospital in Singapore on Friday with his wife, Grace, and close family members at his side.
He is survived by Grace; a daughter, Bona; two sons, Robert Junior and Chatunga Bellarmaine; and a grandson.
Mnangagwa said the country will mourn their former President who was in power for 37 years until he is laid to rest.
“Zanu-PF, the party which the late president founded, has met and accorded him national hero status, which he earned and deserved,” Mnangagwa said at a press briefing on Friday.
Mnangagwa worked closely with Mugabe, first as his assistant and bodyguard in the late 1970s before becoming one of his trusted cabinet ministers and vice-president until their fallout in 2017.
He eulogized Mugabe, whose health had deteriorated early this year and who was flown to meet doctors in Singapore from time to time – with the government footing the bill.
Several countries hailed Zimbabwe’s late ex-president Robert Mugabe on Tuesday as a liberation hero but western powers said he was a bloody dictator who tortured and killed his own people.
