Truth behind what looked like a portrait of one very happy family: Prince of Wales' official 70th birthday photograph was 'absolute nightmare' because of difficulties with brothers, biography claims

The photo released in 2018 featured the heir to the throne sitting on a bench with Prince George on his knee, and the Duchess of Cornwall and Princess Charlotte next to him

Standing behind were Prince William and Kate, with the duchess holding Prince Louis , and Harry and Meghan

A source said it was difficult to arrange as 'neither William nor Harry made much of an effort to make themselves available', with authors of the book describing Charles and Harry's relationship as 'complicated'

Meanwhile, Meghan saw Prince Charles as a father figure - and he was equally fond of her, the book claims. She is said to have formed such a close bond with Charles that she considers him her 'second father'
