A company in which Cosatu's investment arm Kopano Ke Matla had a stake in was not involved in the implementation of e-tolls, the trade union federation said on Wednesday.
"Raubex, the firm in which Kopano Ke Matla has a three percent stake, was involved in the construction of roads that were later e-tolled, and not at all in the implementation of e-tolls themselves," the Congress of SA Trade Unions (Cosatu) national spokesman Patrick Craven said in a statement.
This followed a report in The Times newspaper earlier that Cosatu was "embarrassed" when it was revealed that Kopano Ke Matla had a stake in a company that was benefiting from the e-tolling of roads.
Last month, it was reported that Raubex won a tender to build the R21, which formed part of the Gauteng Freeway Improvement Project.
Raubex received R800 million for the project.
Kopano Ke Matla would have received R24 million as a result of its three percent share, according to the report.
