President Cyril Ramaphosa criticised Ministers in his cabinet for “unbecoming” behaviour on social media after a spat unfolded over electronic road tolls in country’s richest province. Finance Minister Tito Mboweni, Transport Minister Fikile Mbalula and Gauteng Premier David Makhura exchanged words on Twitter after giving conflicting messages on the issue of e-tolling. Many motorists have refused to pay the charge since its introduction in 2013.
