Mineral Resources and Energy Minister Gwede Mantashe says that the untimely passing of deputy minister Bavelile Hlongwa has "robbed the country" of energy in the future."When she was appointed deputy minister I told everyone I want to work with her because she is silly, because I am equally silly."Our combination was going to break mountains and I think this premature death has robbed the country of energy in the future," he said outside the Hlongwa family home in KwaZulu-Natal on Sunday. Hlongwa – who was appointed deputy minister of mineral resources and energy in May 2019 – died in a car crash on the N1 from Polokwane on Friday.

I will miss that complementary character because once you are complementing one another, you are a team. Once you are a team, you are stronger and I am going to miss that a great deal," he explained.
