Prince Harry must “apologise” over one remark to be “accepted” by King Charles, an expert has said.

Angela Levin, who wrote a biography of the Prince in 2018 after spending a year with him, told Sky News Australia the Duke was rumoured to want to return to the UK, while Meghan Markle remained very much against the idea.

But if Prince Harry was to achieve this, first he’s got to “he’s got to apologise hugely, and he’s also got to compromise,” she said. “He won’t compromise – he keeps saying he wants the King and Prince William to apologise for things going right back to childhood, when William got five sausages and he got four.

“It’s that sort of pettiness as well as him feeling very badly dealt with.mIf he wants to bring back a family argument, you have to spend time.

“You can’t rush here, spend half an hour, and then rush away, it takes weeks, months even. Of course, he’s very much under Meghan’s thumb, and he will listen to what she says.”
