Murerwa joins vice-president John Nkomo who is also currently in South Africa on ill health. Murerwa, currently the Lands resettlement minister was flown to South Africa earlier this week after his situation deteriorated rapidly.
Murerwa once fell ill in 2003 which saw him resign from his cabinet post in 2004.
“It’s really not looking good for Herbert,” a close source said.
“He has been ill previously, but this time he was really bad.”
Murerwa also resigned following his “unworkable relationship” with central bank governor, Gideon Gono during the time when the Reserve bank governor was most powerful more than cabinet ministers when he was printing money.
His departure to South Africa also comes weeks after another cabinet minister Eliphas Mukonoweshuro died while receiving medical attention in the neighbouring country.
Deputy prime minister, Thokozani Khupe, was also flown to South Africa was diagnosed after being diagnoside with breast cancer.
Senior government officials or even President Robert Mugabe always prefer to receive medical attention outside the country as local hospitals do not have enough medical equipment, medical experts and medicine.
