Nevertheless, many analysts said the judgment might prove a fatal blow to Zuma, although factional battles within the ANC would be the ultimate decider. One suggested that powerful ANC members had lost faith in Zuma and might move to oust him at a more opportune moment. The South African Communist Party, part of Zuma's own Tripartite Alliance, had been skeptical about the adequacy of his response to the judgment. Some ANC members booed Zuma at his next subsequent appearance. And several prominent members of civil society and former ANC insiders, including Ahmed Kathrada, Ronnie Kasrils, Trevor Manuel, Cheryl Carolus, and retired Constitutional Court judge Zak Yacoob, called for Zuma's resignation, prompting a backlash from certain Zuma allies. The South African Council of Churches did the same, saying Zuma had "lost all moral authority". The Gauteng ANC, led by noted Zuma critic Paul Mashatile, formally resolved that Zuma must resign; doubts were raised about Zuma's leadership even within his traditional strongholds like the ANC's Limpopo branches; and an internal ANC memorandum sent by party veterans to the Top Six allegedly demanded Zuma's recall and compared him to detested apartheid-era President P. W. Botha. Finally, members of the Gupta family, thought to be Zuma's long-standing allies and crucial financial backers, resigned from their major holding company and fled South Africa for Dubai in the week after the judgment – leaving Zuma, in the opinion of some analysts, extremely vulnerable. In the wake of these developments, Malema said it was now time to "crush the head of the snake". On 12 April 2016, Max du Preez said the key question, "now that the balance of power has turned irrevocably against Zuma", was how to ensure he makes a managed – and non-violent – exit.
