The African National Congress (ANC) on Monday conveyed its "heartfelt condolences" to the people and government of eSwatini on the passing of its Prime Minister Ambrose Dlamini.

His country, Africa's last absolute monarchy, announced that the 52-year-old Dlamini had died while under medical care in a South African hospital, where he was being treated for Covid-19.

Dlamini announced four week ago that he had tested positive for Covid-19.
