JOHANNESBURG (Reuters) - South African President Jacob Zuma said on Saturday allegations of private businesses wielding undue influence in his government will be investigated by a judicial commission of inquiry. The country s High Court ruled on Wednesday that Zuma must set up a judicial inquiry into state influence-peddling within 30 days, upholding the findings of a graft watchdog report entitled  State of Capture . The report focused on allegations that Zuma s friends, the businessmen and brothers Ajay, Atul and Rajesh Gupta, had influenced the appointment of ministers. Zuma and the Guptas have denied all accusations of wrongdoing. Zuma was speaking on Saturday at the start of a weekend conference of his African National Congress that will vote on a new party leader.
