Grace Mugabe, Zimbabwe's millionaire former First Lady forced from power in last year's coup, has not paid her farm workers for months, despite living a luxury lifestyle paid for by the state she and her husband once ruled.
Workers on the Mugabes's network of Zimbabwean farms - several of which were appropriated from white farmers - have not received salaries for three months.
Robert and Grace Mugabe have a vast property portfolio in Zimbabwe and South Africa worth more than €60m.
Despite being ousted last year, the Zimbabwean state still spends millions flying the couple by private jet for medical treatment in Singapore.
Zimbabwe's government also said this week that it would not extradite Mrs Mugabe (53) to South Africa, which issued an arrest warrant last Wednesday for allegedly attacking a 21-year-old model with an electrical extension chord in a Johannesburg hotel last year.
Mrs Mugabe is deeply unpopular in Zimbabwe, where she was seen by many as a free-spending, greedy, aloof and arrogant puppet master operating in the shadows behind her husband.
Known as 'Gucci Grace', her excessive spending - including on Rolls-Royces - was shamelessly flaunted while millions went without basics amid grinding poverty.
However, her 94-year-old husband, who can reportedly no longer walk, still has many supporters among the people and in the government. Zimbabwean officials are unlikely to move against Mrs Mugabe while her husband is still alive.
South African prosecutors allege that Mrs Mugabe burst into a hotel room where her sons, Robert Jr (26) and Chatunga Bellarmine (21) were drinking with Gabriella Engels, a 21-year-old model.
Mrs Mugabe allegedly struck Ms Engels with a power chord, leaving her with injuries to her forehead and to the back of her head, as her sons looked on. She faces up to two years in prison if convicted on charges of grievous bodily harm.
South African police allowed Mrs Mugabe to leave the country, which had become the base for her second home, after the incident when she claimed diplomatic immunity. Her diplomatic status was revoked by a South African court following last year's coup which forced the Mugabes from power.
Zimbabwe's deputy information minister said his country would view any attempt to extradite Mrs Mugabe as "harassment".
"We will not smile on any attempt to embarrass, ill-treat or diminish the image of former president Robert Mugabe or his immediate family members," they said. "An attack on Grace Mugabe is an attack on the former president... our founding father and liberation icon and his misery is undesirable to us."
Emmerson Mnangagwa, Mugabe's replacement as Zimbabwe's president, pledged to continue supporting the Mugabes's generous pension package which includes healthcare for both of them in Singapore.
The couple dislike commercial travel and so Mr Mnangagwa hired private jets several times this year which flew Mr and Mrs Mugabe directly from Harare to Singapore's exclusive Gleneagles Hospital. The medical treatments and travel cost Zimbabwe at least €30m this year.
Zimbabwe cannot afford to import basic medication for its public hospitals and most state medical staff, including senior doctors, are on strike over poor wages. Sources close to Mrs Mugabe in Singapore say she "spends money like water". The Mugabe cash is reportedly held outside the country.
Mr Mugabe bought a farm in 2000 but went on to seize a further four adjoining properties from white farmers, who were expelled without compensation. They employ 100 workers across 12 farms.
The state ran the farms for the Mugabes and also secretly bought Zimbabwe's most successful dairy in 2003 for Mrs Mugabe from a white farmer. She invested heavily in the dairy, but it has never yet covered its costs.
Most of their rural assets and the two expensive schools built by Mrs Mugabe on appropriated land are no longer fully operational since Mr Mugabe was ousted from power in last November's coup.
Farmers told reporters they were hoping Mrs Mugabe would pay them by Christmas Eve.
"We are worried for the last months, but we got a message we will be paid next week," said one worker.
Mrs Mugabe, her associates, and the Zimbabwean government, did not respond to requests for comment.
