Up to 100 RAF aircraft from across the generations will perform a flypast over central London during the ceremony on July 10.
Emily Nash, Royal Correspondent at Hello!, wrote on Twitter: “BIG royal outing: The Queen, Prince Charles, Camilla, William, Harry, Meghan, Andrew, Edward, Sophie and Edward will attend a service at Westminster Abbey to mark the centenary of the Royal Air Force on July 10, ahead of #HarryandMeghan's visit to Dublin.”
The service is set to strengthen Meghan’s growing relationship with the Queen, who honoured the Duchess by inviting her to accompany her on a trip to Cheshire earlier this month.
The roaring aircraft formation is scheduled to pass over Buckingham palace at 1pm and will be made up of the most varied range of RAF aircraft in aerial formation since the coronation of the Queen in 1953. Read More from EXPRESS.
