Ms Andrews added: “Yet over the past two years, the two men have become much closer, their bond much stronger.”
Explaining how the father and son have come together with a “shared purpose” following the fallout from Prince Andrew’s withdrawal from public life and Meghan Markle and Prince Harry’s exit, one aide said: “He’s giving William much more input.
“He realises that his own reign will be a shorter one than his son’s, and therefore it is crucial that William is involved in all long-term planning.”
