IFP founder and president emeritus Prince Mangosuthu Buthelezi has again tested positive for Covid-19.
His family confirmed the news on Monday.
His first test with the virus was in August last year.
The traditional prime minister to the Zulu monarch has begun self-isolating at home for the mandatory period.
His family said they were grateful to know that Buthelezi was double vaccinated and would be monitored by a capable team.
However, during this period of self-isolation, the family has requested members of the media to kindly respect their space.
They rest assured that they will keep them informed of his return to work.
