Now that Prince Harry and Meghan Markle have departed for a new life living partially in Canada, there are two vacant roles waiting to be filled in within the royal family.
Royal biographer Robert Lacey, who is the historical consultant for The Crown, thinks Princess Beatrice and Princess Eugenie will be asked to step in.
"It's quite clear that one of the consequences is that Beatrice and Eugenie will now be brought forward – if they're willing to be brought forward," Lacey told HELLO!.
"If two go out, two have got to come in, and those two have got to be Beatrice and Eugenie. I'm sure they will step forward and be greatly welcomed. It's what the family needs as it's another 15 years before Prince George's generation steps up. It's ironic that Harry mentioned his cousins as models of how he wants to be."
