Queen Elizabeth II will host a meeting with her grandson, Prince Harry, on Monday in an attempt to solve the crisis triggered by his announcement that he and wife Meghan Markle were stepping back from the royal frontline.

Other senior royals, including Harry's father Prince Charles and brother Prince William, will take part in the meeting, which will be held in the Queen’s private Sandringham estate in eastern England. Markle will join the meeting via conference call from Canada.
