President Cyril Ramaphosa instructed Transport Minister Fikile Mbalula and Mboweni to work with Gauteng Premier David Makhura to come up with a solution to the e-tolls impasse by end of August.
In his tweet, Makhura said he will refer the scrapping of e-tolls to the president for consideration to make the final decision.
Ramaphosa said the public spat between Mboweni and Makhura on social media is unfortunate and deeply regrettable.
Presidential spokesperson Khusela Diko said Ramaphosa wants the ministers to work together and not against each other.
“No challenge is solved through conflict but rather through collaboration. He trusts that the consultations will come up with a solution.”
