In Zimbabwe, if a person dies without a will, the assets are divided between the spouse and children. Mugabe is survived by his wife, Grace, and four children.
The UN’s World Food Programme (WFP) had said it plans to more than double the number of people it helps in Zimbabwe to more than four million. Nearly eight million people overall are in need, it added.
The WFP will provide rations of cereal, pulses and vegetable oil and a protective nutrition ration for children under five.
“We’re deep into a vicious cycle of sky-rocketing malnutrition that’s hitting women and children hardest and will be tough to break,” said WFP Executive Director David Beasley in a statement.
“With poor rains forecast yet again in the run-up to the main harvest in April, the scale of hunger in the country is going to get worse before it gets better.”
Zimbabwe is currently going through a severe economic crisis, with rising inflation, compounded by a drought across southern Africa.
It had been hoped that the the post-Mugabe era, under President Emmerson Mnangagwa, would bring a change in the country’s economic fortunes. But the current government has been accused of economic mismanagement and human rights abuses.
