Johannesburg - The Gupta family's leaked emails confirm the depth and extent of their parasitic influence on government, the South African Communist Party said on Friday."This barrage of emails we have been seeing over the last days clearly confirms the position of the SACP, but broadens the understanding of the depth of parasitism, rent-seeking, the scale of it," first deputy secretary Jeremy Cronin said on the side-lines of the party's central committee meeting in Johannesburg.The emails leaked to the Sunday Times and City Press indicate the family has influence over President Jacob Zuma, his family, Cabinet and several state-owned entities.They allegedly offered former finance deputy minister Mcebisi Jonas and former African National Congress MP Vytjie Mentor Cabinet posts.The SACP was the first member of the ANC-led tripartite alliance to call for a judicial commission of inquiry into state capture."The scale of the activities we are seeing, the shadow state that we are seeing as said by the South African Council of Churches, correctly we believe, all of these are indications of what some have called a silent coup."SPECIAL REPORT: Gupta emails'High levels of criminality'Cronin called on the Hawks and the National Prosecuting Authority to investigate the information in the emails, which appear to indicate "very high levels of criminality".They reveal that former communications minister Faith Muthambi sent a confidential Cabinet memo about the broadcasting digital migration policy to the CEO of Gupta-owned Sahara Computers, Ashu Chawla.The SACP is preparing for its elective conference in July, at which it would likely decide whether or not to contest the 2019 elections on its own, instead of backing the ANC.Some party members fear the ANC could lose those elections because of the scandals around Zuma and the ANC NEC's failure at its meeting last weekend to recall him.The failure to recall Zuma was an indication of the paralysis within the ANC NEC and among its top six leaders. The party was no longer able to lead the alliance, Cronin said.The party had called for Zuma to step down and said he was not welcome at their July conference. They invited Deputy President Cyril Ramaphosa to represent the ANC instead."It would be hypocritical of us on the one hand to call for Zuma to step down as state president and then invite him to our conference. It would be uncomfortable for him as well," Cronin said.Tripartite alliance relations are at an all-time low due to the SACP and Cosatu rejecting Zuma. The alliance is expected to meet next week in an attempt to heal divisions.
