He was jailed for 32 months in October 2015 after admitting to a string of historical sex offences against teenage boys and young men between the 1970s and the 1990s.
The report, Abuse of Faith, found that Ball, then bishop of Gloucester, suggested “on many occasions” to the former Archbishop of Canterbury Lord George Carey and others that he “enjoys the status of confidant of the Prince of Wales”.
He “sought to exploit his contact with members of the royal family in order to bolster his position, particularly in the eyes of Lord Carey and others from whom he hoped to receive sympathetic treatment,” the report says.
The review into how the Church of England dealt with the case accused Lord Carey and other senior church figures of having “concealed” reports of Ball’s offences. It was revealed Lambeth Palace failed to pass on six letters of allegations of sex offences to the police.
Criticising Lord Carey’s response, the report said he “set the tone for the Church’s response to Ball’s crimes and gave the steer which allowed Ball’s assertions that he was innocent to gain credence”.
The report found Ball made sure Lord Carey knew about his correspondence with Prince Charles and that he visited Highgrove House, the family residence of the Prince of Wales and Camilla, the Duchess of Cornwall in Gloucestershire.
Upon his retirement Ball, alongside with his twin brother Michael, who was also a bishop, rented a house from the Duchy of Cornwall.
But the review went on to say it “found no evidence that the Prince of Wales or any other member of the royal family sought to intervene at any point in order to protect or promote Ball”.
Following the publication of the report, Lord Carey said he accepted the criticisms and apologised to Ball’s victims saying he “gave them too little credence”.
The Archbishop of Canterbury Justin Welby, who described the report as “harrowing reading” and decried “inexcusable and shocking behaviour”, has asked Lord Carey to step down from his role as an honorary assistant bishop in Oxford following the report.
Rev Dr Steven Croft, Bishop of Oxford, has confirmed Lord Carey has “voluntarily agreed to step back from public ministry”.
