Queen Camilla left guests of a royal outing 'feeling awkward' after a break in protocol, an expert has said.
Along with King Charles, she met with authors, actors and lovers of literature at a private reception for the Reading Room Literary Festival over the weekend.
The event at Hampton Court Palace featured stars including Derek Jacobi, Richard E Grant, Dame Judi Dench, Gyles Brandreth and Dame Joanna Lumley.
