Cape Town - The Congress of South African Trade Unions (Cosatu) on Wednesday called on the government to release its research into a possible cap on the fuel price.
In a media release, Cosatu lamented the "massive fuel price hike" of R1.34 a litre which took effect at midnight on Wednesday.
"It is becoming blatantly clear that our inept government does not have a solid plan to lessen the impact of these fuel hikes on consumers," Cosatu's parliamentary liaison said.
"The government promised a review of the fuel price structure in November 2018. Since that promised review, the public has heard nothing from the state. In the meantime, the fuel price has been increased three times with another massive increase predicted for May."
The trade union federation said the fuel price increase was an "anti-poor tax".
