King Charles’ decision to invite ex-Prince Andrew’s daughters Beatrice and Eugenie to the annual pre-Christmas lunch at Buckingham Palace yesterday was a “softening up” exercise ahead of them likely joining the king on Christmas Day, The Royalist has been told.

Charles keeps inviting and including them because he thinks it is a way to project unity and continuity, this time via the familiar tableau of an extended, eccentric, slightly batty royal family gathering beneath the gilded opulence of BP. It’s meant to be a signal that, whatever storms rage inside palace walls, the House of Windsor endures.
