South African President Cyril Ramaphosa said on Tuesday only a united African National Congress (ANC) can help resolve the challenges facing the country - including the persistent electricity load-shedding problems affecting the economy. "We can only confront those challenges if we are a united organization,” Ramaphosa said in his speech on the final day of the ANC conference. This as the ruling party remains deeply divided after it re-elected him as leader despite anger over a growing scandal about an alleged theft cover-up at Ramaphosa's farm.
