Economic Freedom Fighter (EFF) leader Julius Malema's wife and children live in a luxurious house owned by alleged tobacco smuggler Adriano Mazzotti, EWN reported.
The house is reportedly situated in a high-security Hyde Park estate and is owned by Mazzotti, who is a director of cigarettes-manufacturing company Carnilinx.
As a member of Parliament, Malema has an official residence in Cape Town, but lives in the Hyde Park property when he is in Johannesburg.
Mazzotti has had a long-standing friendship with the Malema.
In 2014, Mazzotti paid the R200 0000 registration fee on behalf of the EFF ahead of the general elections.
It was also reported by City Press that Mazzotti helped Malema settle his tax bill.
For about four years Malema had been at the centre of a protracted battle with the South African Revenue Service (Sars) over his tax affairs - at one point he was said to owe the revenue service R32-million and at another point R18-million, News24 reported.
In July, author Jacques Pauw alleged that Malema had received a R1-million loan from a business associate of Mazzotti and, in doing so, he may have unknowingly accepted the proceeds of crime.
Mazzotti "categorically denied" that a donation by Carnilinx to the EFF involved money made as a result of crime.
Malema told News24 at the time that his tax affairs were settled in full – and he had even received a refund on his tax return.
According to EWN, the exclusive Hyde Park estate has four houses in it.
"Mazzotti has a stake in three of them and also lives in the estate with Malema’s wife, Mantwa, and their children as neighbours," it has reported.
Mazzotti told EWN that Malema’s wife pays a market-related rent to live in his property.
The EFF has recently faced more allegations of benefiting financially from illegal activity.
In August, Mazzotti denied settling Malema’s tax bill. "I'm being assessed by Sars at the moment and I suspect they are going to hit me hard," he said.
"I won’t be able to afford these payments," he told City Press.
Malema refused to comment on his tax bill, saying it was "nobody’s business" who was paying it.
In November, the Democratic Alliance opened a criminal case against Malema and EFF deputy leader Floyd Shivambu, Shivambu's brother Brian, and Malema's cousin, Matsobane Phaleng, for alleged criminal offences in relation to the looting of VBS Mutual Bank.
The charges include the acquisition, possession or use of proceeds of unlawful activities, in terms of section 6 of the Prevention of Organised Crime Act, and corruption in terms of Section 3 of the Prevention and Combating of Corrupt Activities Act.
This followed a report by Daily Maverick which stated that Malema, Shivambu and the party itself benefited from the wide-scale looting of VBS Mutual Bank.
The report revealed details of how money allegedly flowed from VBS to a company run by Brian, called Sgameka Trading, and from there to another company called Mahuna Investments, owned by Phaleng.
The EFF, however, maintained that the claims were false and that there was no material evidence supporting the allegations.
