The 41-year-old royal misfit has long struggled with the monarchy's strictures, shaking off the angry young man and "playboy prince" tags only to find himself at loggerheads with his closest relatives.He and wife Meghan Markle -- who together swapped Britain for California six years ago -- return still estranged from Harry's heir-to-the-throne brother William and wife Princess Catherine.Whether their ties can be repaired -- as appears to have occurred with Harry and his cancer-battling father, King Charles III -- was just one of many questions swirling as their self-imposed United States exile ends."I think one of the motivating factors for this return ... is reconciliation with the king and with the wider family," royal historian Ed Owens told AFP. "If those wounds are not healed it can have a really detrimental impact, not only on the people concerned but also on the reputation of the institution."'Lack of trust'The feud has tarnished the family's image. The monarchy has faced allegations of racism and bullying, among others, potentially alienating a younger, more diverse generation of Britons.The image of Harry and mixed-raced Meghan are highly divisive in Britain. According to polls, they attract more negative opinions than any other royals, barring his scandal-plagued uncle, ex-prince Andrew. "They've got to come to terms with the lack of trust in Britain," royal expert Richard Fitzwilliams told AFP. "They've said some very unkind things about Britain, and also about the monarchy."
