Ramaphosa says the two departments will be merged after the 2019 elections. Ndabeni-Abrahams was the deputy minister of telecommunications. Nomvula Mokonyane, who was the minister of communications, is now the minister of Environmental Affairs. SCROLL: Ramaphosa announces Cabinet reshuffleThe former minister of telecommunications Siyabonga Cwele is the new minister of Home Affairs. The changes to Ramaphosa’s executive happen on the day where he was due to reply to an application, brought against him by the DA. The opposition party went to court to challenge his appointment of Bathabile Dlamini as the Minister in the presidency and Malusi Gigaba into the Home Affairs ministry. Dlamini, however, has survived the changes to Ramaphosa's cabinet Molewa death, Gigaba resignation Ramaphosa had two vacancies to fill, following the death of Environmental Affairs Minister Edna Molewa and the resignation of Malusi Gigaba from his role as Minister of Home Affairs.Molewa died on September 22. A month later Ramaphosa appointed former Reserve bank governor Tito Mboweni as finance minister, after accepting the resignation of Nhlanhla Nene.Nene's resignation came after it was revealed during his testimony at the Zondo commission of inquiry into state capture that he lied about meeting the controversial Gupta family, which is at the centre of allegations into large-scale looting in government.In November Gigaba, after attempting to stage a fight to keep his job amid calls to step down, resigned a day before Ramaphosa was due to take “appropriate action” against him as per the recommendations made by Advocate Busisiwe Mkhwebane. The Public Protector’s investigation had found he had lied in court, violating the Executive Members’ Ethics Act. This was in relation to the Fireblade aviation saga.Both the Supreme Court of Appeal and the Constitutional Court also upheld an earlier finding that Gigaba had lied to the High Court.Earlier this year Ramaphosa indicated during his maiden state of the nation address that he was not happy with the size of his cabinet and would seek to reduce its size, merging some departments in the future.
