Prince Andrew will not appear at Trooping the Colour today - while Meghan and Harry secure a last-minute slot.
The Duke of York, who stepped down from royal duties in the wake of a sex scandal, may still attend a Service of Thanksgiving at St Paul’s cathedral with family members tomorrow.
Andrew denied the allegations against him and he later came to an out of court settlement with his accuser. The settlement is not an admission of guilt.
Meanwhile, the Duke and Duchess of Sussex will watch Thursday's parade from a balcony above Horse Guards parade before going back to their home in Windsor, while others may join the Queen at Buckingham Palace.
Their appearance follows the monarch encouraging everyone to revel in her Platinum Jubilee celebrations throughout the special bank holiday weekend, declaring: “I know that many happy memories will be created at these festive occasions.”
