The Democratic Alliance says it commissioned the billboards erected along Johannesburg's highways next to the e-toll gantries.
DA's Gauteng premier candidate Mmusi Maimane confirmed at the weekend that the billboards belong to his party.
The billboards, visible along the N3 and N1 highways, poke fun at the African National Congress and its role in the electronic tolling saga.
The message on them reads: "E-tolls. Proudly brought to you by the ANC."
Maimane said the message was "100 percent accurate" and it was difficult to see why the ANC was upset.
He said the ruling party had lodged complaints with the Advertising Standards Authority and Independent Electoral Commission but that the DA would defend its right to erect
the billboards in any forum the ANC chooses.
