Since Meghan flew back to North America last week, Prince Harry has been speaking with the Queen, Prince Charles and Prince William about his and Meghan's future in the royal family.
During the gruelling two-hour talks, the Queen told Prince Harry she wanted him and Meghan to continue their work as full-time members of the royal family, a suggestion the couple knocked back.
In a strikingly personal statement released after the summit, she said: "Although we would have preferred them to remain full-time working members of the royal family, we respect and understand their wish to live a more independent life as a family while remaining a valued part of my family."
And while admitting there were "complex matters" to resolve, the 93-year-old monarch said she was "entirely supportive" of Meghan and Harry.
She has since ordered aides to make final decisions "in the coming days".
Prince Harry is expected to attend a royal engagement at Buckingham Palace on Thursday and then fly back to Canada to be with his wife and son.
