Trade union Cosatu has thrown its weight behind Gauteng Premier David Makhura who maintained during his Sopa last week that he will scrap the tolling system, sparking a massive debate on the issue.

The union's Amos Monyela told eNCA on Sunday that e-tolls is another form of tax, which isn't fair treatment for the province's motorists.

On how the debt, which has reached billions, should be settled, if not through the system, he said finance minister Tito Mboweni must devise an alternative plan which will see the debt being paid.

"The minister must come up with the alternatives of making sure that this thing is paid. So when we pay for e-tolls it means we are now triple taxed and that is unacceptable. This is why we have been consistent that they must look into other alternatives."

According to Makhura, e-tolls will soon be a thing of the past.

"We remain determined to ensure that e-tolls are not part of the future of our province. We are even prepared to contribute something as the provincial government to ensure the e-tolls are scrapped. There is no turning back," reiterated Makhura.

But this did not sit well with Mboweni, who on Thursday last week, posted a series of tweets, some which have been deleted, saying the system should have been introduced with the understanding that it needed to work for government, in that it would yield profit in the long term, as it was an investment.

"Now therefore, the user must pay Premier Makhura!!", exclaimed Mboweni.

Transport minister Fikile Mbalula chimed in, in an effort to rein in Mboweni, by asking that they discuss the matter privately so they would give the public a unified response, as instructed by President Cyril Ramaphosa.

Makhura stuck to his guns as he dismissed Mboweni's rants in an announcement that he had engaged with President Ramaphosa, and Mbalula on the matter.

On Saturday, Mboweni told the Sunday Times that he would be meeting with the ANC leadership in Gauteng, upon his return from Rwanda, Kigali to discuss the matter further.

Presidential spokesperson, Khusela Diko, further told the publication that President Ramaphosa disapproved of the social media spat, saying their actions were "regrettable."

"The president regards the public exchanges between minister Mboweni and the Gauteng provincial government as most unfortunate. As leaders, they have failed to conduct themselves in a manner befitting the stature of their offices and the high regard which society accords them, and this the president finds deeply regrettable."
