The story
Until the 1960s, Illovo was a subsidiary of the General Mining Company of South Africa, which sold a 49% shareholding in the business to Tate & Lyle in 1969.
This was then sold in 1977 to C G Smith (Sugars) Ltd of Natal. Today it is a subsidiary of Associated British Foods Plc., which purchased 51% of the issued share capital for more than £400m in 2006.
In 2016, ABF bought the remaining 49% of the company's share capital.
