The case is the third and final one brought by the Duke of Sussex in his acrimonious legal battle with British tabloids.

The High Court in August ordered Harry and six others, including pop legend Elton John, to make an initial payment of £9.5 million to Associated Newspapers Limited (ANL) after finding against them a month earlier.

Harry, the 42-year-old younger son of King Charles III, and the other claimants were seeking to appeal on grounds that the judgement and costs ruling were "legally and factually flawed", a statement sent to AFP by law firm Sheridans said
