Buckingham Palace officials took great care in trying to avoid a repeat of the frosty scenes when the Sussexes and Cambridges sat near each other and left together at their last joint event in March 2020 at Westminster Abbey. They had been at St Paul's Cathedral for the service, but were kept apart from Prince William, Kate, Prince Charles and Camilla after royal aides ensured they sat on the other side of the aisle - and they later left separately. The Duke of Sussex was seen smiling next to his wife while being driven in a Range Rover with another car carrying security personnel behind, after what was the couple's first joint royal engagement in two years. Prince Harry and Meghan Markle returned to their Windsor home of Frogmore Cottage this afternoon, leaving the rest of the Royal Family to attend a reception without them following the Service of Thanksgiving for the Queen.
